Someone might enjoy the whole long story with its emotional roller-coaster; this is totally fine. I personally skimmed a few paragraphs, realized that it's not what I enjoy spending my time on, and closed the tab. I find it also perfectly fine.
The fact of that a story is high on the HN front page is an endorsement, but not a guarantee that you in particular would enjoy it. At least I hope the author enjoyed writing it.
There's a million different writing styles. No one expects every book in the library to be written to your particular taste. But for any piece of writing submitted to HN, if it deviates from a dispassionate, terse, action-filled style, the tl;dr crowd come out and start ordering people "don't write" like this.
