You don't need to explain to me how the Fediverse works and I never said I have any expectation of privacy. But generally speaking, you're overlooking the fact that there always have been rules for what can, and cannot be done with information that is publicly available. Just because someone publicly posts his Facebook profile picture doesn't mean it's legal to use in an ad without permission, for example. People might break the rules, yes, but then they might face consequences, and that alone prevents many from breaking them in the first place. Not perfect, but better than nothing. And I'm saying we're in a process where rules are being renegotiated when it comes to using public information for AI training
