Threads has begun testing federation over ActivityPub. And they have blocked two important servers I administrate. The first server is the Mostr Bridge. The Mostr Bridge connects ActivityPub and Nostr together, so people can communicate across protocols. The second server is Spinster.xyz, which is arguably the largest independent feminist community online.
XMPP works well and the community is actively developing server and clients. There aren’t any big corporations funding it anymore that’s all. Still the best instant messaging protocol in 2023.
Well that just furthers the basic point.
