Lol, bro, my incapability or your lack of clear communcation? Modifying a quote of my comment is about as obtuse as you can get.

GNUSocial had an XMPP plugin, it was not built on Jabber. Yes XMPP clients have microblogging built out, but still lack some competitive features to the Fediverse, and fundamentally are still a server-based ecosystem rather than a self-hosted p2p ecosystem for persistent content which is what my post was discussing.
