@mcc am having a discussion of this on bsky that is helping to disambiguate :
https://bsky.app/profile/futur.blue/post/3lyuzwzb2k226
also https://github.com/zeppelin-social/bluesky-appview

@mcc nothing is stopping blue sky from blocking the h other two instances right ? Also is it not the case that black sky has an incomplete view of the entire atmosphere like only a few days so it's still dependent on blue sky due to the high cost of infra for being able to contain that entire view ?
