XMPP seems very good to me, unfortunately it's not used by many (except for the closed source fork: WhatsApp), and the userbase is only furry and weebs.

Also Matrix is kinda ok, main issue is the clients being a bit slow/slugghis/bloat, but the experience is still better than entering any Discord server IMHO.

Whatsapp is a fork of XMPP?!?!?!

[–] [email protected] 12 points 4 years ago* (last edited 4 years ago) (1 children)

Yes, they run a protocol called FunXMPP. WhatsApp used to be an independent company, and they just used the industry standard and improved it a bit. Moxie (of Signal) then later added something that inspired also XMPP OMEMO e2ee on top of that.

That said... Facebook messenger also used to be XMPP, but they moved to MQTT, and there have been constant rumors that Facebook plans to merge the two. Maybe it will happen with the new multi-device feature that is soon in beta.

P.S.: Zoom is also XMPP :p

Can they do that and not publish the source code?

[–] [email protected] 7 points 4 years ago

Yes. XMPP, the protocol, is just an open standard. If theyve implemented their own version, they can ise any license they want.

If they forked an implementation, on the other hand, there are some limitations depending on the license. But even if the server was forked from GPL code, they dont need to publish the server code.
