That aside, I find it offensive a little bit that Meta has taken it upon themselves to decide what the "right" discourse is that their users want to see, and would rather they create a mechanism to let users decide for themselves - which this does at least outwardly appear to be a move towards. They've also in the last few years toned down or removed some of the auto-modding in private groups, and shifted that responsibility towards its community members and moderators - which was also a similarly good step.
that's very different and a case where the closed community should bear that responsibility
but as far global FB community -- which doesn't really exist (there is no "community", just users) -- or, more precisely, what ends up in people feeds, the fact checking was a good thing because a lot of people consume news that way; so this is a big step in the wrong direction
