You're right, of course, that off-topic shallow dismissals are bad comments for HN.
Unless of course HN holds content promotion deals with big titles - then users who care are *.
Usually when people say an article has "little to do with hacker news", they either mean that they don't personally like it (which is fine, but not relevant at a site level) or that it has nothing to do with technology or startups (but HN's mandate is explicitly to go beyond those: https://news.ycombinator.com/newsguidelines.html).
That doesn't seem excessive to me.
