At first glance I think it's a kneejerk reaction. Most of the people here are pretty tech savvy and are here because they're not interested in centralised systems, so they're going to be able to decide on their own whether or not to block company-owned instances.

But... there's precedence there. Facebook/Meta might not have the trail of bodies that Google has but I don't think anyone is foolish enough to think there's anything sincere or philanthropic in their motives. The fact that they're putting everything behind an NDA seems directly opposite to the entire ethos of the fediverse, which isn't a great start.

I think an abundance of caution wouldn't be a bad thing. I stopped using Facebook because it degraded so badly and they kept overstepping boundaries. It would be a real loss if the same thing started to happen here.
