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.
But the question of how to handle politics on HN is not simple. By the same principle of trying to optimize for curiosity, some content with political overlap is interesting and belongs here. The questions are which forms of it, how much, which particular links, etc.. I feel like after 10 years we arrived at a pretty coherent and stable general answer to that. Not that we get every specific call right—we don't. But the general principle has held up.

and there are lots more at https://hn.algolia.com/?dateRange=all&page=0&prefix=false&so... covering this.
It would be an absolute treasure trove of how to manage public forums and social media, especially as it evolves from a small niche community to a larger one, maintaining as much of its original character as possible, and in a highly politicized, adversarial, and mis/dis-info saturated information environment.
Would be a fascinating read.
Let's look at the specific topic you mentioned. HN had plenty of discussions about the lab leak theory, starting in late 2020 and all through 2021. I've listed some below; there were others (and of course many more in 2022 and 2023). Some fell off the front page rather quickly but the biggest ones spent 15, 16, 18 hours on the front page.
Everyone's memory about the pandemic has been retroactively revised by now, but as I recall it, the rehabilitation of the lab leak theory in (semi-)mainstream discourse began when Nicholas Wade published his article in the Bulletin. HN discussed that one thoroughly (>>27071432 ) and there had been several major frontpage threads even before that.

(There of course were many threads arguing the opposite as well - I'm just listing these because they're the relevant ones for answering the GP. If this post makes you feel like HN was too supportive of and/or too suppressive of the opposite side, please re-read the first paragraph - it seems to work the same way in all cases.)
