I agree with your point. Metaface is the most hilariously transparently bad actor on the internet. That well is so poisoned there's no olive branches that will save their reputation. The incentives for these companies are clear and produce a consistent pattern: build something useful and start building walls around it so you can exploit whatever you've built to produce the most shareholder returns. Any instance that cooperates with a Bookmeta instance is willfully ignorant how it will end, even if MaceTook truly does not have malicious plans at the start.

But beyond the other responses, I think it's worth thinking deeper on this. It's easy to reduce it to "It's simple. We kill the Zuckerberg."

There have always been bad actors, and will always be bad actors. There are probably bad actors in the room with us right now. If this whole threadiverse experiment is going to survive, it needs to be able robustly handle them even when the bad actors can bring a lot of resources to bear.

Also the real fun happens when TheMeta.Com starts proposing changes to ActivityPub. Even if the changes are purely technical and make perfect sense there's going to be slapfights.
