"The man who killed Google Search" is too baity. See the 'unless' in https://news.ycombinator.com/newsguidelines.html: "Please use the original title, unless it is misleading or linkbait"
Edit (since there are objections): I'm not taking a position for or against the article; I haven't read it. This is just bog-standard HN moderation regarding titles. I skimmed the article looking for a representative phrase and couldn't find one on first pass. That is rather unusual and when it happens I sometimes ask the community for help.
Edit 2: since there's no consensus on this I'm just going to reify that fact via the trailing-question-mark trick and call it a day.
