It is like countries setting up an Embargo. If instances know they might get defederated by helping expand metas influence they will think twice.

Basically Meta will try to join the fediverse build up a bunch of users and get content. Once they become the biggest instance they will build up a wall to kick all the competition out. It is what google did to XMPP. https://ploum.net/2023-06-23-how-to-kill-decentralised-networks.html By signing the anti fedi pact we are esentially preventing a corporation from taking over and ruining it for everyone else.

Twitter has an office in Boulder? Makes sense I thought Elon was living under a rock.
