is this just how Blue Sky is? I don’t browse it much outside of David’s threads.
Not in my exp. Standard is also to just block annoying people asap so they don't show up in your replies/other peoples feeds. The blocking function is very strong on bsky. (I do worry that the more 'influencer' types (or people who just don't care) will not block annoying people because it drives more views to their content, so that is why you would find more of those comments under something from Evans than a random poster).
Lot of people also have the 'do not show things to people not logged in' feature turned on.
Friend of mine was surprised I had never heard of some popular 'right of repair' guy who now also went anti genAI, as he thought I would have heard of him because it was a lot of overlapping circles.
