I have no idea if that was true 20 years ago, but it's not true now. XMPP doesn't have this problem; your host instance knows your IP but you can connect via Tor.

Tor has the problem that you frequently don't know who's running all the nodes in the network. For a while the FBI was running Tor exit nodes in an attempt to see who messages were being sent to. maybe they still are.
