I would argue the opposite. Often the comments that OP is describing are people who have very little knowledge of the topic at hand, only strongly held emotional feelings based on some narrative that appeals to their bias.
The problem is, HN is a crowd of people who grew up believing they would all become the next Steve Jobs...a decade or two later, the chips have fallen, and most of us have not become that (yet many have had to watch their former peers become wildly successful). So what we have now is a community of bitter, frustrated, and resentful people hurling those feelings onto whatever the topic of the day is.
Instead of accepting your jealousy and failure to achieve [insert desired outcome], it's much easier to believe that...whomever or whatever becomes successful...is doing so not out of merit, but out of deceit. By placing yourself on a higher moral pedestal, you avoid the pain of direct comparison. Ex: Sure, [insert person or company] is successful, but it's because they prey on [insert moral failing of both the product and the people who desire it]!
