I’m worried this will not be enough in the long run.

Imagine Meta provides more original content, a higher user base, more engagement, more activity. That alone would make it interesting for many other users, further increasing their relative attractivity.

Additionally, they could invest in the codebase, and implement some of the community’s dream features, some nice mod tools, search engine discoverability and whatnot. On a fork which lives on their instances, of course. Services which work if you federate with them.

They have the resources to rase the stakes higher and higher. The incentives are objective, real, advantages for users, communitites, mods and admins. Isn’t it only a question of time / stake height until significant parts of the fediverse choose to cooperate for various reasons?
