Activitypub and the matrix protocol are different things, they aren’t supposed to interact with each other. Matrix servers using matrix implementations (synapse, tuwunel, conduit, etc) can interact with each other, since they are all based on the same protocol. Same way we do it, how AP servers with mbin,piefed,lemmy interact all with each other, since they are all based on the same protocol, too.
Revolt doesn’t federate at all. They even admit this.. I stand corrected on rocket.chat, they actually implemented the matrix protocol, so it’s interoperable with matrix.
I think your last point is flawed, since even with multiple revolt instances; they don’t interact at all. Which, is not federation. Matrix is federated, there’s no other way to look at it and they’re not comparable, and not meant to be compared at all.

What do you think Federate means? It absolutely does, Matrix Federates over the Matrix protocol, which is a separate protocol from Activitypub which is what Lemmy and Mastodon use. It doesn’t Federate with Lemmy and Mastodon because they are different protocols but it absolutely does federate. Honestly there’s no reason for it to Federate with Lemmy and Masotodon. ActivityPub isn’t a good protocol to use for chatting, Matrix as a chat protocol is superior. Not to say that activitypub is bad, it’s great for social media platforms like forums and blogging, it’s just not good for instant messaging.
