From the HN guidelines:

> please use the original title, unless it is misleading or linkbait; don't editorialize

I'm finding myself disappointed with the application of guidelines here. The title has been changed to a completely made up headline, differing from the original, which is editorializing. It's the second time this happens in the past 24 hours - yesterday the ".. you idiot" part was removed from a blog post completely numbing the post's intention. Neither was misleading or clickbait.

EDIT: while typing this comment, the title has been changed yet again to reflect the paper's title "Effect of Colonoscopy Screening on Risks of Colorectal Cancer and Related Death".
