Have you read through the thread? Tons of examples of admin abuse. I fully expect to cop another ban for this comment thread soon.
Also, I would disagree with calling defederation 'censorship'. Nobody was prevented from speaking up. Refusal to engage with somebody you disagree with is not censorship.
Preventing people from interacting with whole instances is the ultimate form of censorship. Deleting comments is nothing compared to literally deleting all the users from one instance.
