A growing number of instances (mainly of Mastodon so far) are signing an ‘Anti-Meta Fedi Pact’, pledging to block any instance owned by Meta in the fediverse.
I don’t know how big this will get or how effective it will be, but if you run a fediverse instance, you should take a look at this https://fedipact.online/
Wait, are you saying there’s a chance Meta isn’t Meta?
Because I’m at least 99.9% sure of that information, and if accurate there is no need for any further information.
If you have reason to suspect that Meta somehow aren’t themselves, but candy unicorns, please tell me. That kind of intel would be pertinent.
