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.
And when people say they want it discussed, they don't mean they want to read diverse opinions, they just mean they want to see orthodoxy regurgitated.
I wasn't really interested in all those Reddit stories last month either, mostly because they were all exactly the same wankfest. So I just hid them. Problem solved.
As long as the frontpage isn't overrun with these kind of stories every day I don't really see the problem. Even when restricted to purely technical topics – and HN is NOT for purely technical topics – there's will always be heaps of stories you won't be interested in for one reason or the other, and that's fine.
