Seems like you didn't really understand my point. Meta is very averse to, for example, any NSFW content, or using words that aren't G-rated to talk about other people. I do not think there will be a slow creep of Meta federating with server by server, because I do not think 99% of servers are willing to abide by those restrictions. If you want me to make up numbers, I think Meta will federate with 10 servers, at most, and that's it.
The other part of the equation, from what I understand, is authorized fetch. If servers implement that, that prevents Threads from accessing their content from a middle-man server if defederated.
So no, I don't want to federate with them. But I also think that writing off kbin because Ernest hasn't already defederated is a premature, knee-jerk reaction.
