I would say it is not about writing style but more about the personality of the author. According to MBTI for example, people are either Thinking (T) or Feeling (F), and I would imagine that strongly Feeling people focus much more on emotions (as compared to Thinking people) when expressing anything - be it talking, writing, etc. To them, the expression of emotion towards a particular subject is as important, if not more, than the objective value / knowledge / information imparted.
I can also hazard a guess that there are more Thinking people lurking in HN vs Feeling people, thus the general repulsion towards that style of writing.
