@mike This is untrue. There are a number of independent apps across various verticals. Blogging: leaflet, pckt, offprint; Streaming: stream.place; Short-form video: spark; Git: tangled; and so many more, and none of them are directly dependent on Bluesky whatsoever.
This doesn't even count the microblogging competitors coming up that are full-stack independent of Bsky as well (Blacksky, Northsky, Gander, Eurosky etc.)
