I got around 5 links deep for each of the links in the admin's post, and fuck if I know. There was an argumentative user, but they were articulate and thoughtful. Not dropping slurs or wasting space nonsense, but still bordering on "edgy". The person pushing the defederation appeared to be bullying them and on a power trip.
It was embarrassing. That's all I took away. (My opinion can change if someone digs through the shitpiles of nothingness to pull up some actual naughty posts, but that's not going to be me.)
