ActivityPub wasn’t built with the purpose of having a “killer app” in mind. That’s centralization logic. The point is for all apps to be able to talk to each other regardless of where on the network and maintaining the ability to do so seamelessly without the user having to think too much about it.
Mastodon should be able to talk to Lemmy. Lemmy should be able to talk to Pixelfed. Et cetera. I don’t believe XMPP had the same purpose, matter of fact I remember it just being a subpar IM protocol iirc, and I don’t see social media going by the wayside the way IM clients of the past did.
