So, recently some fediverse admins (mostly Mastodon) and the founder of Mastodon, Eugen Rochko (Gargron), where contacted by Meta/Facebook for an NDA meeting. We know nothing about it, but we're pretty sure that it was about this project92 thing that Meta/Facebook is creating to "compete" with Twitter.
So a lot of Mastodon admins already singed a pact to immediately block any Meta/Facebook activity in the fediverse as soon as it comes up. My Mastodon instance, fosstodon.org hasn't singed that pact and I'm pretty worried.
The following image is an screenshot of Gargron and dansup (creator of Pixelfed) talking about this. These posts were deleted, even from the wayback machine.
To me, the introduction of Meta to the fediverse means exposing everyone to a large poorly moderated community that would ruin the current culture of the fediverse. The best way for people to protect themselves from the inevitable onslaught of hate/prejudice/threats, the kind that’s typically found on Facebook but somehow “not against community guidelines”, is to preemptively block the upcoming instance. As for the NDAs, they are a great way to sow distrust within our own instances and try to tear us apart.
