In capitalism it's mostly the customer's responsibility to switch when a company becomes too-evil in some way. Depending on your politics you could, perhaps, argue with some truth that network effects make that extremely difficult for social media sites, so the only solution is to have the government extensively regulate FB, twitter, etc, but I am not entirely convinced. IIRC FB engagement with teenagers and early-20s folks is already declining noticably in the US (though there probably are multiple reasons for that beyond just privacy concerns).

Usually a replacement comes along to make it easier.

Slack vs irc

Facebook vs myspace vs geocities

> Or developers and companies could self regulate, because they care about other people.

I hope this is sarcasm.

Not really but probably should have been
