Yep, if you are on either, you are fighting the good fight, so keep it up :)
I will! It is a really nice setup for me.
And if you self-host, you’ll find it dramatically easier to do on XMPP (that’s how I ended-up here, after giving up on Matrix’s shenanigans).
Interesting, but I got past that hurdle... and I made it extra hard for myself as I didn't use the ansible playbook but instead created my own docker setup (own as in writing a docker-compose.yml myself, not as in creating the containers from scratch). But this way I understand the system and could fix problems that I had myself rather nicely.
