Nope Nope Nope.

I don't agree with OP creating infighting within the fediverse, but I really do agree with his points on defederating.

Have you heard of the term "Embrace, Extend, Extinguish"? It was Microsoft's motto in the 90s to early 2000s of destroying free and open source competition.

The first step: "Embrace" meant to embrace the competition's protocol. Things like the Open Document Format, or in this case ActivityPub. They would make a product that used that protocol, pretending like they were contributing to it.

The second step: "Extend" meant to extend the protocol. They would divert from the way the original protocol worked, and adding more features that would attract the users on the original platform to their one. They would do this in a way that the original platform wouldn't be able to catch up and get feature parity with them, such as making their new protocol closed source.

The final step: "Extinguish" would be that when enough users migrated away from the competition's original platform, they would basically have stolen all the users, profited off the volunteers that made the original product, and made a worse, closed source, non-free alternative.

I know it's pretty fucked up, but this is an actual thing that happened, and it's not just Microsoft. Google's done it with XMPP, and Facebook is probably doing it with Threads this time around.
