True. But still there is usecases to use it save. When I for example create an XMPP user via tor, my end can hardly deliver identifying data.
But for sure in every conversation I am only relyable for half of the metadata.

Tor is networking. XMPP OMEMO does not hide who the sender and reciever are
But it has no way to know who they are. And the messages are encrypted. Through Tor, the XMPP server can not even know from which country you are.
The server knows the usernames of both parties. The metadata
Yes. But it is everyones own freedom to choose a username. So I hope we are not using this freedom to put anything about our real live into this username.
Right now you're talking to me with a picture of you on Nostr. If you were to write in your bio your XMPP username, then any random person on the internet can see it's you. Now the XMPP server sees your life. This means if you want privacy, you should run your own XMPP server.
Can you get some privacy by using others? Yes of course
Totally agree 👍
