The problem here is that you're talking about the comments on the submission, whereas I was not. I'm talking about the upvotes on the submission.

It's entirely expected and unsurprising that Apple's announcement of a major macOS release would receive a ton of upvotes, regardless of how people feel about the release. That's why I think your analogy is irrelevant.

A low quality submission should not receive many upvotes, and as a consequence, it should not receive many comments of any kind, positive or negative, because it won't appear on the front page of HN for people to notice and comment on it.
