Ok so, here I am again asking another question 🙈🙊
But hear me out: I read this post here about, if there even is a good privacy messenger that can be trusted. Someone in the comments mentioned Conversations (a XMPP client for Android). This made me look into XMPP and at the moment I am giving Conversations a try.
Reading into XMPP, I couldn't find a problem security or privacy wise. Also it seems like it does not matter what server I use (atm. we are on 07f.de) since it is all e2e with OMEMO. Am I missing something or is it really this good? And if I dont trust anyone, I could host my one instance of ejabberd, right?
XMPP can be very unsafe. It depends on the client you use. Its best to use a protocol that doesn't allow unencrypted messages to be sent at all. Like Wire or Signal.

This is an implementation thing and not a protocol thing. What protocol doesn't allow unencrypted messages? I am sure signal's protocol would still allow it, it's just that the implementation doesn't.
And same for XMPP. Just go with the implementation that doesn't.
