We don't need the pitchforks just yet, sure, but shit, you have to remain realistic about these things.
Your words, not mine. I never made such claims, and you're trying to move the goalposts from "Meta does this" to "I'll be surprised if Meta does this".
I think you mean "I'll NOT be surprised if Meta does this", which is the reasonable position of any rational person to take.
I'm allowed to extrapolate expectations of future behaviour, based on past behaviour. Doing otherwise is naive, dangerously so if you're responsible for someone else's security or privacy.
And I truly believe Meta has an incentive to do so. They had to reveal a conversation on Facebook Messenger on the topic of abortion after the police asked for it, which resulted in someone put in jail. Regardless of Meta's (or rather Zuck's) ever changing political position, they don't want to have liability over anything like this. They want to walk away and just say to the cops, look it's all encrypted, there's nothing we can share with you.
Better keep conspiracy theories to yourself. It's ok to question things, but better back that up with evidence.
When you have a history of doing greasy shit, you don't get the benefit of the doubt.
