The real community federation standards are XMPP and ActivityPub. If you want to break the monopolies of the big social media companies then it is those you should support, not some badly done enterprise Slack clone like Matrix or Rocket Chat.
I agree with that, but there’s been cases of XMPP and ActivityPub providers shutting down federation before.
