Facebook is already a bad actor on its own platform. They are not going to be any different with the Fediverse. The meeting under NDA for a select few instance admin is already pretty fucking sus. Not just because it looks similar to union-busting tactics, but because that’s exactly how it started with XMPP before they crippled it.

And even in the unlikely event that I end up wrong, what benefit would federating with Facebook bring us? We don’t need them, and as a company their only purpose is to make profits, not to make Fedi better. There is no positive outcome possible for us, no matter how you slice it. We need to defederate before they even get a chance to do anything.
