I've made a list of 23 threads (see the reply below), all from the last month. There are over 13k comments in those threads alone, and it's not a complete list.
It's interesting how claims like "only non-controversial stories" or "no discussion of this sort shall be allowed" (https://news.ycombinator.com/item?id=42976817) arise during periods when there's a sharp increase in such threads (https://news.ycombinator.com/item?id=42978572).
At first that seems counterintuitive (like Jevons' paradox, or Yogi Berra's "nobody goes there anymore, it's too crowded"). But it's not so paradoxical. These aren't factual propositions, they're expressions of a feeling—what people are really saying is not that there is no coverage of these topics, but that they would like more coverage. They often use words like "no", "zero", "never", and "nothing" to express how they feel, but what they mean by these words is "not enough". Which is fair enough. The community always splits between users who want more and users who feel like it's too much.
Also, it's easy to miss any particular thread or sequence of threads. Even among regular HN readers, there will be many who haven't seen even one of the 23 threads listed below, or who only saw 1 or 2, and therefore might naturally feel like none of this is being discussed. Among those, there will be some who feel strongly about it, and some of these will naturally express their feeling in the way I described above. Nonetheless, in reality there is a large amount of this discussion happening—it is by far the most-discussed topic of recent weeks, and will likely continue to be.

Sorry for giving that impression! I often add a disclaimer like that because I don't want to sound like I'm making excessive claims about HN's discussion quality. The most I can say is that median discussion quality here is modestly better than elsewhere on the internet, but at its worst it's still pretty bad. I don't mean to put down HN commenters who are using the site thoughtfully. You have to remember that as moderators we see a lot of stuff like https://news.ycombinator.com/item?id=43018472, to pick the most recent example. In fact we must see more of that than any other reader, simply because it's our job to.
