I have noticed this trend for a long time also, and well before this article was first written. It seems to go in waves though I'll cautiously say that it seems to have gotten somewhat better in recent years. I remember a time in the mid-2010s when these kinds of stories would disappear almost instantaneously. Now some of these articles and topics get a good number of upvotes and occasionally even substantive dialogue.
That said, the comments sections on these articles do tend to devolve pretty quickly.
Your comment history mostly shows comments on non-technical stories. Why is that?
Some people will use HN for job postings. I would certainly expect that anyone with two brain cells to rub together uses a throwaway account for anything but the most boring opinions about C++ proposals. All it takes is a single throwaway sentence 7 years ago that pisses off the Church, and you could end up not getting hired.
