So the responsibility should lie, as usual, with the people at the top, who set the direction for the company, not for low-level peons like engineers, who might be highly compensated, but the engineers don't set the direction for the company nor make the ultimate decisions regarding these algorithms.
But part of the tragedy of organizations is that responsibility tends to be diffused, so it's really hard to ultimately blame any one person.
There was a documentary (maybe called "The Corporation" or something) which showed some protestors outside some CEO's home, and the CEO's wife went out with some tea and cookies or something and invited the protestors inside their home to have a chat, and the CEO talked to the protestors and told them how helpless he himself was, as he was just part of the system with relatively limited ability to change it.
I'm not sure I buy that, and not sure the protestors did either, as the CEO still has enormous power. At the very least the CEO has the ear of the board of directors, and quite a lot of leeway as to how to run the business. They might not be able to change it all, but they can change a lot. Still, there's no denying that especially in a large organization no one person knows everything that's going on and can be accountable for absolutely everything, but leadership still exists and still is ultimately responsible.
Precisely. Nobody should accept that kind of obvious nonsense.
People are put into positions to make decisions. So make better decisions.
The biggest reason they are bad is that they don't work. I would happily subscribe to a concierge service that showed me genuinely useful information. However, the advertising systems we have got are not built for my use case, they are built for someone else's which is adversarial to mine. I could not possibly care less about your quest to build brand loyalty and awareness.
As noted, people often get shown ads for products which they have already bought. When I buy a car, it's a safe bet that I don't need another car for several years. Every car advertisement that I see in that time is wasted effort for both the advertiser and myself. I also notice that nobody is advertising along the lines that might influence my choice. As a single, eco-conscious male, I don't need "three rows of seating" and I need "low zero to sixty" times even less. Automobile advertising is heavily devoted to the highly profitable SUV segment. Eliminate the Chicken Tax and promote decarbonized and efficient vehicles. Stop basing advertising campaigns around stoking even more antisocial behavior.

And the flip side, people getting shown advertisements for products they have rejected is also wasted effort. I don't need penis pills, and every advertisement I have ever seen for them has always been wasted effort.
Stop polluting my information streams with awful crap I don't need.
Nobody likes being watched. Instrumenting the interaction that I need so that you can make wrong inferences about my preferences is pretty galling. Undermining my control over what information I do give out is worse.

Further, not specific to targeted advertising is the method of advertising. Advertisements in popup windows are a terrible idea. Forcing me to take an action before giving me useful information is a terrible interaction model. And that's not designed to make me want to buy your product. Advertising when it exists should be as unobtrusive possible. Obnoxious behavior sucks.
