I know a lot of people think Musk is simply a mustachio-twirling comic book villain so there's not a lot of critical thinking ever applied to this sort of story, but even still, he'd have to be an order of magnitude dumber than buying Twitter, to think they could just train on all browsing data and that people would be chill about it.
