>but then you'll have to face the consequences (de facto social isolation) and probably acquiesce.

Nah I'm used to being lonely. Leaving these platforms shows how few truly deep friendships you have.

You get used to it.

>I had the same reaction when platforms started asking for my cellphone number... after some years I just started giving it to them.

Even when I gave Facebook my number, that wasn't enough. I drew a line at some point. If everyone else wants to sacrifice privacy for the sake of pseudo-community, so be it.
