I'm sorry! I misread you. I thought "Try harder next time" was a swipe at another user, which it wasn't.
(But https://news.ycombinator.com/item?id=11979795 and https://news.ycombinator.com/item?id=11963888, the other comments I had in mind, did break the site guidelines, so I still need to ask you not to do that.)
That title is indeed bad, but I've explained why we haven't banned the article here: https://news.ycombinator.com/item?id=11981664. Also, if we had, people would accuse us of trying to suppress criticism of a YC-funded startup, which is something we err on the side of not doing.
