I reject the claim of "mental gymnastics" as a meme bereft of substance, and specifically in this instance, as an unproven hypothesis. But even if I granted the inference, I don't see how overly elaborate argumentation could have any explanatory power for the trustworthiness (or otherwise) of major platforms.

I'm curious, why do you think I'm advocating trust in any platform? And I'm curious why you think that I have any concern one way or another for an "exodus" from any platform?

Really, I'm just replying to say that while I think I understand the gist of the tone of your reply, I don't actually understand anything you wrote. And my hope is that you can clarify, because — and I say this with all sincerity — I really am genuinely curious.
