One of the reasons I moved to this instance was that during the first announcement .world didn’t want to defederate Facebook. That and the extensive block list, I can do that for myself thank you very much
I'll probably block it, but if they bring a large number of users and communities, that comes with content more people want to see.
I'm ambivalent about decisions to defederate because both have merits. Cut them out completely to protect the community, or let the users choose who and what they want to block for themselves. I guess with that in mind, I'm fine with the "wait and see" approach for now.
