I haven’t hosted my own matrix server yet. is it safe to join an instance? I don’t really know how private that would be. the question is when I signup/login would I be giving out my IP? is the metadata private? sorry for asking this, I’m just a bit paranoid
you have a point there… maybe I should just use XMPP+Mumble server for voIP. I’ll avoid matrix as for now as long as it has many privacy holes. and I already know how to use XMPP over tor which is convenient.
how is XMPP’s end-to-end encryption though, I heard alot of varying opinions on that.
For me e2ee on XMPP with OMEMO works fine, never had problems with it. But I guess your best experience will be if both sides use the Conversations client on Android.
