There's weird cases. In my DnD group only one person has not switched to Signal and they refuse to. Their answer is that "I can't fight them so why switch?" Which weirds me out since this is exactly how you fight tracking. Btw, this is someone who has a PhD in computer science so it isn't like they are tech illiterate. But I've seen several people like this and honestly I don't understand.

I think at this point a lot of people are now apathetic and have given up. And we know people like to double down on good or bad positions when faced with adversaries. Doing things like "switching to Signal" (when you already have most of your friends there) and "using an adblocker" seem like very simple things that easily respond to "what can I do about it?"
