Matrix is a shitcoin. A protocol that relies on bridges as a major feature is garbage.
XMPP is older and more proven, and is not in the hands of a French business living on grants from the government.

You're very hard with Matrix 😅
I use it to access communities not hosted on discord or Telegram and the experience is pretty nice. Regarde the bridge stuff I suppose you won't like Beeper.com so 💀
