I’m confused by this - there are various things Meta might want from the Fediverse (free content, more data, more people to serve ads to), but new users can’t be one of them. No one from Mastodon is likeky to migrate to Meta’s platform; the people who want to use Meta are already there.

Anyone operating an instance should defederate from this shit immediately. This is exactly the kind of corporate overreach that isn’t welcome here. This will end very poorly for the fediverse I think.
