Meta actually did the same with mastodon, a lot instances blocked them before federation was turned on. People who use Lemmy are not likely to be up for a tech bro to be federating with them.

That said I'm sure you'll be able to find and join an instance that would do it if you want it.

It would be horrible and kill this place. Meta does not do any sensible moderation on its platforms. There are nazis on there. All those MAGA propagandists. Scammers. Trolls. Meta is doing nothing against that.

A "meta lemmy instance" integrating Facebook groups would be too big for other instances to block. Which would bring all those users you really don't want to be here into our forum with no moderation. It would also send all your posts and user data from here to Meta.

I refuse to believe anyone actually uses the word 'fantastic' unironically.
