Idk what to tell you. If you prefer how it is on activitypub then use activitypub. I barely ever use bluesky and mainly use lemmy snd mastodon. I think having no say in who you’re defedersted from sucks. Its why lemmy lets users block a server now even though mastodon doesnt. This is good.
Lol “just leave the art server” is terrible for artists and also 90% of people have no idea what defederating is and wont ever know theyre defederated from X server. I think its way better for servers to set their default blocklists that block the server they dont like and users to be able to choose to opt out of them, add more blocklists, etc.
