It's genuinely annoying that all allegedly "not evil" messaging platforms suck ass
Signal? Kinda okay, decent UX, but annoyingly simple and visibly only made for 1:1 chats. And painfully mobile-only.
Matrix? Would post about it but sorry can't decrypt message. No seriously, no matter how hard the fanboys want to convince you "it's good now, actually!" it's not. There are still random, unacceptable problems.
XMPP? Sure, go ahead and use it you and your 2 friends. Even among OSS people, it's a huge niche.
Honestly, what else is there?
Idk, i still use Matrix and have hope in the project, but maaan
Oh and ofc talking to communities of any of those projects is an experience about as nice as eating shit
