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/
Give Meta an inch they’ll take a mile. No quarter. No wait and see. No half measures. We don’t literally know nothing; we know Meta is involved. That’s enough for me to say no.
They’ll follow the Microsoft route, pretending to be for open standards, then extending the standard for only their apps and sites, and with sheer numbers and money they’ll grab a bunch of users who will come to expect the features and implementations they provide and then bam. No more fediverse.
Not. One. Inch.
Well yeah, but there isn’t any indication that they’re modifying the standard at all. ActivityPub is still it’s own thing that they will be presumably tapping into, what I get from the current info is they are just creating a kbin/Mastodon competitor which should be its own thing entirely.
