I seem to recall that sometime in the early years of Fakebook Mark Zuckerberg was actually quite boastful about an “end of privacy” kind of theme, where he was being quoted dismissing privacy as some antiquated notion being obliterated by technology. I was surprised that there was not a lot more push-back at the time.
Eric Schmidt at Google said something similar, so I quit using Google to the best of my knowledge. I don’t use gmail or Chrome. Ditto with FB. They were busted some years ago for doing unauthorized research on their users. Never had a FB account and certainly wasn’t going to get one after that.
