I want to break a local community free from Signal, and I've been thinking about XMPP. In reading some analyses I found this gem:

I stopped using Signal because I just don't trust it. Why so many updates with no explanations? Is it so unstable and insecure that it needs them? Also, check out search results for running your own Signal server. Technically it's free software, but practically, good luck.
So I guess I need to figure out persistence and E2EE for XMPP, and land on a server and clients. I'm inclined towards ejabberd, because Erlang!
I'd welcome thoughts.
