Eh, this person hasn’t really HNed imho. If the tone and tenor of the comments get you, then whatever, it’s toxic for your appetite, move on.
There’s really a deeper darker underbelly of HN where certain opinions get down voted without explanation. It’s the quiet silencing or shunning. In fact, the person that wrote this article is kind of the person that would quietly down vote, not partake in the discussion, and then one day write a blanket ‘you are all toxic post’, like a serial killer that confesses.
