Ok so let's get a few things straight.
1. "Big admins" complaining about the community being pissed at them for meeting with meta under NDA is their fault and their fault only. Some admin blocking mastodon.art for being vocal about this is bullcrap. If you could not anticipate the fact that bragging on Mastodon about having a secret private meeting with Meta would spark anger, that's on you. Isn't the first rule of NDA "do not talk about NDA", by the way ?
2. Meta has no good intentions, they don't plan on "playing nice" with smaller actors. Thinking otherwise is very naive. They plan on nipping potential competitors in the bud and make a profit. If they cared about anything else than big players and their user base and wanted to embrace the Fediverse as a concept, they would not discuss their plans only with big actors behing closed doors would they? They're trying to "join" a community that identifies as a healthy alternative to them and start with an NDA. What. Could. Go. Wrong.
3. Meta is the company that allowed meddling with elections. They're the company that slowly removed from your timeline everything you loved to replace it with things they think you would be stupid enough to click on. They're a company that followed suit with Musk's "premium verification" concept to propose a similar product. There is NO REASON to trust meta and "wait and see". We ALREADY KNOW that Meta is evil and have had proof over and over.
4. How arrogant do you have to be to think that once you allowed a company like Meta in your garden, you could reverse everything and undo any harm they're doing with "just 2 clicks" (sic) ? This is hubris.
Block Meta. "Big admins", in their arrogance, are playing a very dangerous game for all of us and they did not consult the community before doing so, which is kind of telling as well.
