@halva she literally called him a "hack" for implementing features on blacksky that work exclusively outside the atproto network- i believe for followers-only posts, which blacksky's community deeply desired, and atproto very much Does Not Support out of the box
this is like if a fedi instance implemented a feature outside of the activitypub protocol (as i hear, this happens all the fckn time on fedi), someone called them out for breaking activitypub compatibility, and that someone was then lambasted as being transphobic or some shit
