Oh no, I didn't mean moderators are biased. I don't think that is the case at all.

I was making the point of the HN users. Specially the characteristic of downvoting and negating criticism in this case.

You are right though, because I strongly feel about the anti competitive issues Apple indulges in, maybe I visit those threads more and tend to notice them.

Although, I think there is a positive bias as well, which I care less about. Like one of the commenter mentioned that Final Cut Pro being launched on iPad was the top post through large parts of the day.
