Guidelines say fine to editorialize in these cases.

I think on HN, people waste too much time arguing about the phrasing of the headline, whether it is clickbait, etc. and not enough discussing the actual substance of the article.

I prefer improved titles. However, not in this case. It is rather irony, because LWN does not need click-bait.
