I am functionally a pr dude for atproto (bluesky) on here because people repeat so much disinfo, and I have "someone is wrong on the internet syndrome" 😭
However, atproto and bluesky are still distinct and I am pretty appalled at a fair amount of bluesky's recent decisions, esp this one
Several people have self hosted relays. Afaik nothing that anyone has used in "production", everyone just uses the default one. I expect that will change as people figure it out, and trust in bsky pbc drops with things like the current Turkish censorship incident
Example of self hosting https://bsky.app/profile/why.bsky.team/post/3lkwg2djrfk23
The code to run a relay is here https://github.com/bluesky-social/indigo
