"Deep bias against Zionists..." if that's among the criticisms you feel hold weight in this discussion, I don't see how that is somehow equivalent or worse than whatever is happening in Xitterville. Not only do they openly platform and pay anti-Semites, the platform is owned by one. But you conclude people may have criticisms of Zionists stealing land and murdering people shows bias?
Why don't you go ahead and try posting some anti-Semitic stuff and see how long your account lasts on Xitter vs Bluesky. And if you see that on Bluesky, you can report it. They actually have a safety team. Hell, Alex Winters had his account flagged for SPAM when he was trying to help the citizens of Gaza survive an onslaught from...Zionists.
Again, no, it's not perfect. But it's a hell of a lot better than the alternatives. "Echo chambers" don't improve by letting Nazis in. Maybe some of the not-nazi Conservatives on Xitter with actual reasonable defendable positions should find a home there, instead of hanging out in Nazi-ville. or maybe they just all feel real comfortable on the couch there. That has nothing to do with the Bluesky userbase.

Lots to choose from.
Here's an emulation feed for something more niche:

I feel like you are coming to conclusions before actually using it. When I started I wasn't sold either, but once you start adding what you want to your feed, it works well. Try it for a few weeks. And maybe it doesn't have absolutely all of everything you want, which is fine too. And maybe it's not for everyone. I don't care. But the misrepresentations are garbage.
