There is – jabber and jingle. And for a ver-ry brief few weeks, Google’s jabber/jingle worked openly with Facebook’s, and everyone could message each other. And then BOTH arbitrarily broke it with some sparkle-junkie resume-bait software 'up’grade and neither worked with anything else after that.
It was glorious.

There is: XMPP 🤷

But i also feel like xmpp got feature creeped. Not to long ago, basically every messenger spoke its own subset of xmpp, basically.

It’s not any worse than the differen’t feature support levels of different Matrix clients. But especially on Android, XMPP has nice modern clients with all the features you woukd expect, including a/v calls and reactions/stickers.
The main issue right now are up to date Windows desktop clients, but on Linux desktop there are some good options.
