About this specific case: it set off the flamewar detector (a.k.a. the overheated discussion detector) and also got moderation downweights. We sometimes turn off that penalty, but I don't think we'd do so in a case like this, because HN gets so many posts of this nature. They flare up with Big Drama that is sensational for a while but not particularly interesting, and therefore not really what the site is for.
In fact HN gets so many posts of this type that it has become a joke, and not only that but a cliché, so much so that the top comment of the Reddit thread repeats it [1]. That's about as repetitive as anything gets. The basic idea of HN is to gratify intellectual curiosity [2] and avoid repetition [3].
