Yeah, it certainly feels like this.
But why is that so?
What is it that we don't like about XMPP heterogenity?
Well, it's not quite compatible.

Unless you specifically choose a client and server that work well together, nothing but a basic text chat will work reliably. Any fancy stuff tends to be incompatible.

But then, is fediverse any better? What kinda user experience do you get when viewing a peertube video in Mastodon, other reading and replying with basic text?
