We have regulation that somewhat works (there are exceptions of course and corruption is a thing, but at least there's an attempt) for other negative impacts on society (environmental damage, etc) but absolutely nothing for tech despite these new apps & services turning people into addicted zombies.
It's not just about (B). There is a tricky balancing act involved. A company that does too much (B) ends up with an app that users don't like and stop using. A company that does too much (A) produces a beloved app right up until the point that the company runs out of money and folds.
Because they have to compete with people doing lots of (B), and giving the app away for free. I'm increasingly feeling that "free + ads/surveillance" is the problem.
