I'm fine with users not editorializing the headline, instead opting to use the original title. This is so that no one can accuse the poster from editorializing it themself and allow dang or one of the HN mods be the one to change it.
I can see the reasoning there, but that approach works best when people refrain from posting articles with garbage clickbait titles, in the first place.
The current solution isn't terrible; we don't need to trust the average submitter to come up with a title that's better than the original, and the bad cases tend to get fixed by the mods eventually. Unfortunately it does mean we see clickbait titles in the stream for some time, and the clickbait gets rewarded.
We're also assuming that the article is worth reading despite the clickbait title. If an article has a seriously misleading title, that tells us something about the kind of journalism we can expect in the article itself. Ideally, I'd rather such sites never make it to HN.
