Despite the the "strictly no jesting on the super serious hacker news" rule, I think it was just a joke. I wouldn't let it get to you too much. I thought it was pretty funny.
Honestly I don’t find those kind of comments particularly valuable on HN. It derails the topic from a meaningful discussion and the whole thing devolves into a Reddit troll fest. All you need to do is glimpse at the replies it spawned to confirm it. This is why I assume it was heavily downvoted.
No it's not valuable at all. I'm just replying to a person who got particularly upset by it and seemed to take it seriously. Just ignore them or downvote and move on.
