All the pro-cloud talking points are just that - talking points that don't persuade anyone with any real technical understanding, but serve to introduce doubt to non-technical people and to trick people who don't examine what they're told.
What's particularly fascinating to me, though, is how some people are so pro-cloud that they'd argue with a writeup like this with silly cloud talking points. They don't seem to care much about data or facts, just that they love cloud and want everyone else to be in cloud, too. This happens much more often on sites like Reddit (r/sysadmin, even), but I wouldn't be surprised to see a little of it here.
It makes me wonder: how do people get so sold on a thing that they'll go online and fight about it, even when they lack facts or often even basic understanding?
I can clearly state why I advocate for avoiding cloud: cost, privacy, security, a desire to not centralize the Internet. The reason people advocate for cloud for others? It puzzles me. "You'll save money," "you can't secure your own machines," "it's simpler" all have worlds of assumptions that those people can't possibly know are correct.
So when I read something like this from Fastmail which was written without taking an emotional stance, I respect it. If I didn't already self-host email, I'd consider using Fastmail.
There used to be so much push for cloud everything that an article like this would get fanatical responses. I hope that it's a sign of progress that that fanaticism is waning and people aren't afraid to openly discuss how cloud isn't right for many things.
Now I have to use different apps for Signal, Element, Slack, Discord, WhatsApp, Telegram, ...

I think the effective altruism forum (1) is one of the main reasons why the community is able to have produce so much output.
