When #facebook first came out with React, I was super suspicious. I’d been directly affected by their XMPP/Jabber bait & switch, and was expecting a similar play. But React turned out to be one of the most popular open source projects in history, in large part thanks to Fb’s custodianship.
The product dynamics of #P92 is closer to XMPP than React, but on the other hand #ActivityPub is an inherently more connected and coordinated (albeit loosely) network than XMPP was, because it’s one big room.
