The concept was fine - if it was correctly advertised and (ideally) given multiple options of block list curators like how you can subscribe to blocklists on in Bluesky. That would actually be a great feature, because he was right about one thing - onboarding normies to the Fediverse is a struggle.

Hiding it, actually actively obfusacting it, making it unconfigurable and bundling it with the safety/anti-spam filter is not okay. That is him trying to silently make himself arbiter of acceptable conversation on the Fediverse.

Then on top of that, you add some of the bans he included being deranged at best and possibly actively homophobic and transphobic at worst.
