My point is that it's not misleading at all (and thus not clickbait). It doesn't tell the full story, for that you'll have to click it. Most titles on HN don't tell the full story. Many of them could be suffixed with "in America", or "for Mac" or something like that. Yet we don't do that either.
I never said it was clickbait, that was the GP comment. And if you're going to refer to the guidelines:
"Otherwise please use the original title, unless it is misleading or linkbait."
One could make a reasonable case that the title of the source is misleading because it is incomplete, so the additional specificity may be warranted.
