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/
Having meta into the fediverse is the easy way out. Meta is going to grow like a cancer in the fediverse, enticing weak minded instance owners with a large pool of users to sign a contract to allow meta to implement their ads or their i fluence somehow in order to make their profits.
I dont see why youd want anything like that to take part when its going to be the same bullshit
