Whether someone else also broke the site guidelines isn't really relevant, but in any case the OP of this submission did not break them. I get that you feel the article is bad, but it's hardly against HN's rules to post an article that someone else thinks is bad.

If you see what you feel is a bad HN submission, you're welcome to flag it, but not to post low-information/high-indignation putdowns (let alone violence-invoking swipes) which are clearly against HN's rules.
