I do not want my posts from anywhere on the Fediverse on FaceBook.
I have have seen people express worry over FaceBook posts showing up on the Fediverse. But, what about our posts showing up on FaceBook.
If Meta federates with the Fediverse, do my Mastodon posts (e.g.) show up on FaceBook?
A lot of smaller Masto/Pleroma/other “microblog” side of the verse admins signed FediPact. It’s mostly smaller instances, but there’s still a good amount of them and it’s enough that Meta will at least face some struggles in wide federation.
