"Despite Fraser’s efforts to implement his own PDS, Relay, and App View, however, Blacksky still remains partially dependent upon Bluesky’s application server"
"Blacksky’s continued dependency on Bluesky came into focus on Sunday after a Blacksky user suddenly found himself unable to view his own posts on the alternative site."
