I find their argument (from 2022) about switching instances very uncompelling. Now we have instances fully dedicated to things like NSFW. It makes it a lot simpler to allow folks to block instances than adding more reasons for users to encourage defederating. In the infamous Beehaw defederation announcement they said “all we have is a nuke” and that’s true. It would be nice if users could selectively disable content they don’t like without having to encourage their instance admins to use that nuke.

To be clear, I’m not saying Beehaw shouldn’t have defederated or that this feature could’ve stopped it, I’m just saying their description of defederating as the nuclear option is accurate.
