Which one(s) are you referring to?

I mostly agree with you except that I believe we can change other people. Maybe we can’t change a specific person, but I think (or at least I would love to believe) that we can influence people we interact with, in big and small ways.

Love the detailed answer with all the links, thanks!

And for the sake of completeness, what resources would you recommend to a beginner?

It’s neither. They keep blocking (and unblocking) services tactically to prevent people organising protests.

ActivityPub :) People spend an incredible amount of time on social media—whether it be Facebook, Instagram, Twitter/X, TikTok, and YouTube—so it’d be nice to liberate that.

Probably meant CSAM (child sexual abuse material) instead.
