Well, I think Musk's weird fanbase tend to flag unfavourable St Car stories, but also, well, "new-Twitter is a broken mess" is just getting a bit _old_ at this point. There's only so long that "social network in decline due to poor management" can stay in the headlines.
(See also, HN's coverage of the decline and fall of Digg; started off dramatic, but eventually just slipped away into "wait, that still exists?")
It's not HN trying to do this, any stories critical of Musk or his enterprises usually get flagged by lots of people and therefore tend to stay off the front page. This has always been happening a very long time, the benefit of lots of devoted fans.
