the decentralized nature of XMPP is a huge plus for me.

I guess Matrix also has that, in theory, but from what I have seen the matrix.org homeserver still effectively functions as a central point to track metadata.

I guess the issue with XMPP is that people can send unencrypted messages to you, perhaps with deanonymizing information?

Mainly preference, I don’t prefer it because it isn’t encrypted by default.

I could add a section on XMPP I spose.
