I work in population genomics (non-human organisms), and myself participated in an early near-whole genome genotyping study back when microarrays were still the predominant technology (academic NOT commercial).

But for nearly 20 years I've been telling my extended family NOT to participate in any large scale genotyping with 23 and Me or similar commercial companies where they retain rights to your data, anticipating that something like the current scenario would likely play out.

Somehow, 23 and Me genotyping became the "gift du jour" for Xmas some years back -- I never personally understood that or why someone would want to turn over so much data to a commercial entity.

This is not to say that large scale sequence information is not appropriate for *some people*. But if that's something you need, make every effort to make sure you own your own data.

> I never personally understood that

It’s a pretty simple cost/benefit equation.

For 90%+ of people, the benefit (or appeal) of seeing an ancestry report is greater than the cost (or risk) of handing over your DNA.

That said, it’s definitely fair to question why more people don’t take their personal privacy seriously. The reality is companies like Google (and 23andme) simply wouldn’t exist if everyone cared as much about privacy as the HN crowd. Google exists because consumers are fine with sharing their data, for better or worse.

theptip · 9 months ago
I am extremely skeptical that many people are making an informed cost/benefit here. I would wager most users don’t even know about the license terms.

It’s the same as infosec in general. Most people don’t know about the risks, and anyway are bad at quantifying tail risk.

smikhanov · 9 months ago
It’s not about “the HN crowd”, it’s just that the time has changed so much. Do you remember 2008? Facebook was a swanky way back then to reconnect with your classmates and leave some “Like” things under their wedding photos. Google was seen as a way of organizing the world’s information to make it universally accessible and useful, with their niche ad service being still in limited beta. Twitter was so unknown that it still hasn’t even won a Webby Award.

And 23andMe was already offering a $100 DNA sampling in 2008.

It’s easy to be cynical about this in 2025. Those who didn’t live through the early 2000s, can’t even imagine the amount of optimism surrounding the tech industry at that time. Giving my DNA to a cool new Silicon Valley firm in 2008? Sure, why not, it was like buying a ticket to some utopian future.

This refrain is repeated endlessly but I've never heard a good argument as to why it must be this way and if it was any other way Google simply couldn't exist in any (ideally better) form.

jasonfarnon · 9 months ago
How can someone possibly make a cost/benefit analysis when the future uses of public dna data are so speculative? Criminal in the 70s didn't think leaving their dna around could lead to their arrest 30 years down the line, probably didn't factor in their cost/benefit analysis at all. I guess maybe you could figure there's safety in numbers, if loads of people are in the same boat are you there's a ceiling on your risk (legislation eg). Those of us who grew up in the era of smoking a pack a day don't really feel that way.
CamouflagedKiwi · 9 months ago
But most people don't want Google to not exist. They derive significant value from it - from Google search, from Maps, from Gmail, whatever. I think that the access they have to my data has cost me basically zero, and I've gained a lot.

Had 23andme had access to my DNA, that might be worse in future. Although today there is not immediately a lot of downside, you can certainly imagine futures (maybe slightly dystopian ones) where that turns out to be pretty bad.

aucisson_masque · 9 months ago
I believe it’s more that people don’t see the potential threat and harm into providing sensible data to commercial entities.

People who have been for instance wrongly jailed because Google gave their location history to law enforcement and they happened to be near a crime scene, these people they understand the value of privacy.

But you have to acknowledge these companies started out as something different.

The cost is not static over time. As data storage, laws and AI evolve, the cost of having your data stored somewhere will increase significantly. So if you are making a cost evaluation based on the present situation you are incredibly naive.

> consumers are fine with sharing their data

Google is an advertising company. Google exists because businesses advertise and Google became, overnight in geological terms, the sine qua non of advertising.

Consumers aren’t really OK with sharing gobs of private data, but most don’t have a choice, many enjoy the free shit that they get from Google, most don’t notice or realize how much and what kind of data is collected, and none zero zip nada of us can stop Google from doing it.

This is absolutely nothing new in thousands of years. Businesses have sold and hoarded and collected and traded consumer info since time immemorial. Among themselves, with government, with law enforcement, with criminal gangs, who knows. You’re simply deluded if you think any commercial activity is private or confidential for a consumer. Yes even if you pay with $2 from your cleavage.

tiahura · 9 months ago
The other 10% being wanted criminals?

why more people don’t take their personal privacy seriously.

Probably because this testing has been happening for almost 20 years at this point, and we’re still waiting to hear about someone being harmed. For the most part, the privacy concerns are FUD.

wenc · 9 months ago
I made an informed decision when I signed up.

It's SNP genotyping, which realistically other than telling your ancestry and few health conditions, isn't that predictive of most health conditions. Genotyping only captures a small percentage of total genetic information (it's not a full sequence -- still too expensive for what I paid), and thus the data was actually very limited, so the risk was realistically very small.

Privacy is about risk-reward -- rather than applying the preventative principle to everything (which is overly conservative), we make trade offs in life.

Also, their genetic risk scores and population admixtures are really bad. I can't understand why they are so bad given that they hired pretty good researchers and building these is quite simple. Freely available models run circles around anything they report on their site.

It's a bit like uBiome, they have sold a lot of snake oil and harmed the reputation of B2C tests. It's a shame as something like 23andme, plus a bit of epigenetic testing to capture environmental factors, could be a wonderful way to get an overall health snapshot.

Glyptodon · 9 months ago
Well... My experience (having worked as an SWE) w/ medical technology is that if a company is selling something, they will choose the version of advice or analysis that most aligns with selling something. (I got ordered to adjust scoring thresholds in a statistical grouping to have "nicer" groups, for example.)

If your company does treatment X that competes with treatment Y, they'll look to expenand the edge cases that suggest X over Y as much as possible. If a company wants people to feel like they're getting something out of a genetic profile, they'll report the broadest version of risk, and then slow roll more detailed analysis.

Things like this are why I strongly think certain profit motives and business models should be extremely restricted. Just like private prisons create a profit motive for creating crimes, medical services have a profit motive for spreading inaccurate and twisted medical advice, whether it's things like alternative or new age medicine, treatment modality choices, or DNA information.

robwwilliams · 9 months ago
In the case of 23andMe users do own their data. And if they download their data and then request data be deleted then they are the sole owner. But if interested in genealogy, kinship, and some of the more actionable SNPs (e.g. those in drug ADME) then the 23andMe interfaces is informative and even useful medically. I have uncovered two medically useful variants. And some fun ones too: the speed with which I metabolize caffeine.

Their interface is also better than AllofUs.

It only took a couple of decades of grinding down the public’s perception of privacy.

2000s — PATRIOT Act (and other heinous domestic surveillance acts with no due process) — “wE aRe pUrSuInG tERrOrIsM”

Then the invention of the portable digital camera and subsequent social media between the mid 2000s and 2010s — “selfies” and other aspects of social media made it so much easier for private and public entities to spy on people

Then the introduction of godawful companies like “23andme”. Fortunately never bit the hook and “FOMO’d” into it but rather kept this data between my doctor and myself (and the genetics testing company). Much more expensive, but at least I am covered by HIPAA.

Then last but not least, the introduction of big data companies and broker companies which build profiles on everyone that uses “free” products such as Google search, Facebook, tik tok, and many others that preceded it.

We can’t even escape ads and profiling when we _pay_ for the fucking thing.

I want to say 9/11 changed the game, but in reality I think the erosion of privacy was happening way before that (ie, to serve advertisers)

I work in data. I knew what was at stake. But for me, I wanted my son to have the ability to trace his paternal lineage, should he ever be curious. His dad isn’t part of our lives and lives somewhere in Europe. My mom died before he was born. I convinced my dad to take the test (actual quote: “Obama’s going to put me on a list”), and I took the test too — so that my son could someday deduce his paternal side. I think it’s Polish, German, and Danish, but I’m not entirely sure. I didn’t have him take the test, just wanted to leave him the option.

You'll get it when your insurance company bought your profile and automatically added a ton of pre existing conditions to the list of things they won't cover for you. Or when the government decides to start rounding people up based on ancestry or health conditions.

The problem, not stated, is that a bankruptcy can wipe out the obligations of a company to its customers. This includes privacy obligations.[1] Especially if the assets are sold to a company outside California or outside the US.

Yes. We need obligations to be able to follow personal data, by analogy with real estate (if you agree an obligation with your neighbour, for example access rights, it can be effected in such a way as to be binding against future owners. Otherwise you could get stuck without access each time they sell up. This is often set up at the point when the land is subdivided)

The fact that 23andme is at risk as a going concern tells you what you need to know about the potential of monetizing large amounts of generic data. It turns out you can’t get much value from it. If you could, they would have.

And no I don’t think all of that DNA data would be valuable to the likes of a large health insurer like Humana or Aetna either.

The medical records you are imagining an insurer can link to genetic data are worth even less than these DNA sequences turned out to be worth.

Sincerely,

A former health economist who has worked both with tens of millions of inpatient discharge records, and (separately) a detailed survey which is complemented by genetic data.

unyttigfjelltol · 9 months ago
Candidly, given existing law in the US, the highest use an insurer could make of the data is to opt families into specialized preventative care using the DNA profiles in the database. They might make pretty decent profits taking that angle, and possibly generate significant goodwill.
s1artibartfast · 9 months ago
How would that make them money? Every dollar saved in preventative care is $0.15 less profit, because insurers have a fixed profit margin as a percent of total care provided, due to the ACA's 85/15 rule .

The only reason to to do it would be to compete with a peer insurance company that is already doing it, resulting in less profit for both parties. The optimal strategy from the insurance profit perspective is to ban any DNA based cost saving measures for all insurance companies.

huitzitziltzin · 9 months ago
No.

(Slightly longer answer: I don’t have the funds to match what someone is likely to pay for this data, but if I bought it and gave it to you for free, and also gave you all the inpatient hospital discharge abstracts in the US in a matchable form, plus whatever health data you want, plus family relationships, plus a budget for 100 PhDs, product managers, and marketing people for 5 years you couldn’t turn it into a viable product. (Indeed that is literally what 23andme tried to do for years!))

Calvin02 · 9 months ago
Thank you for sharing.

I have long suspected that the sequencing data isn't valuable except to law enforcement.

If it were as easy to link sequencing to diseases, we would have seen a rapid advances in our ability to address those diseases. The genetic data alone isn't enough of a predictor.

The administration could decide to detain, deport, or kill everyone who has certain traits - say, Jewish, or Arab, or Mexican, or maybe just has undesirable traits. The db of millions of users makes this very easy.

Most people here seem concerned about insurance companies misusing personal data or a full-on totalitarian government takeover. However, my concern is about becoming susceptible to manipulation and coercion. A significant aspect the last election was the use of "Super PACs" like Elon's which targeted individuals on social media to influence their decision.

I think this trend will continue, not just in politics but across all sectors. The internet you experience will be tailored to your personality completely, but it will also be shaped to steer you in directions decided by who pay the most. The more data they collect about you, the more effective this manipulation will be.

This doesn't even account for the risks posed by malicious actors who might target you using this information.

The practice of how this does damage isn't clear to me. But I'm going to test this in the very skin-in-the-game sense. My genome (sequenced by Nebula Genomics) is available to anyone who would like it. I have raw FASTQ files which you will have to pay a nominal fee to access.

Once upon a time, a friend and I decided we should launch a site where people can submit their genomes and health information so that broad population scale studies can be done. I did submit my stuff to All Of Us and so on, but I think the fact that you need to be special-cased to access the data is probably a loss.

So I think it's time to revisit this whole thing. Perhaps I should make VCFs available instead. They're much smaller and may be more accessible for people. In any case, if you want my FASTQs, just email me.

No singular person, it's more the value of having a large database. You visit a coffee shop, a stalker collects your dna from a fingerprint and uses the a leaked or sold database from 23andme to tie it to your identity or home address, etc.

Insurance company sees you have a marker for some chronic illness or cancer or whatever and suddenly you can't get life insurance anywhere or have a massive premium. They could even deduce this if only your parents' DNA is available.

Sure you can delete your data, but guess what, they'll retain it anyways under "regulatory obligations". I've gone back and forth with their privacy team and this is the last response:

    "This is a follow-up from the 23andMe Team. To clarify, we and our laboratory vendors are bound by various legal and regulatory obligations that may necessitate retention of certain information. We want to assure you that our data retention program adheres to applicable legal requirements which can vary depending on what country or state a customer lives in, the state a contracted laboratory is located in, and any applicable federal or state licensing obligations related to the ancestry and health products we sell. We can confirm that samples and genetic testing results are deleted in accordance with applicable law and any legal retention obligation serves as a proper exception related to a data deletion request under data privacy laws."

If 23andme has an agreement with its consumers on how it will handle the data it should not matter whether they are bought that agreement should be maintained in perpetuity unless those consumers actively choose to change their agreement.

After all we wouldn't talk about Dropbox being sold resulting in ransacking of your personal data why is that in the conversation with 23andme?

You're right that it should not matter. That would be a great world to live in! It's not this one, though. Companies ignore these agreements all the time. Sometimes they're even caught and their wrists get slapped.

More often (I believe) we just never learn the agreements have been broken in the first place.

But it is a rule—almost approaching a law of nature—that companies facing financial distress will begin putting a price tag on private data they've promised never to sell. It's like the cartoon with the starving people in the life raft: they look at your data, and suddenly they don't see a legal agreement to protect it, they see a juicy drumstick.

Not legally, they can only do that if you implicitly agree by continuing to use the product.

If you don't interact in a meaningful way you cannot change a contract from one side you need a new agreement.
