That's without getting into the separate tendency that original user-submitted titles (whether or not it matches the article title) often capture the essence of what's actually interesting to the audience here. Subsequent edits then lose that association -- making it less likely that I (or other people) will click through. Linkbait, you say? That's the whole point, I say.
In this case: Sure, the article's original title was hyperbolic. But so what? It's hyperbolic to good effect, and gives a feel for the tone of the rest of the article.
