No weird opinions, you do you and if Matrix suits your needs, great. In general I like the idea and concept behind Matrix, was a bit clunky to get it going initially but afterwards, with Continuiwity as backend server I have to say I ran quite smooth. I guess for a small homelab/self hosted setup with maybe a hand full of users, XMPP sounds easier to maintain. But I guess I’ll have to find out, probably going to deploy Snikket or Ejabberd for a test run.
