Apparently Bluesky people have no interest in this kind of analysis, since it got zero response, but it pretty much nails a major problem I have with this media platform, namely, the cult-like exclusiveness.
You choose the accounts you follow on Bsky. That's one filter. They choose the Twitter posts they share here. That's a second filter. If people on here then scream, "Don't share Twitter posts!!" that's effectively a ban.
