The point is not to save you a click in all circumstances, but to save a needless click due to frustration/curiosity.
I know HN likes to keep the original title if at all possible, but pretty much every clickbait title could be profitably replaced by a clever submitter:
"FCC names Jonathan Mayer new chief technologist for enforcement"
The only other clickbait title I see right now is courtesy the Washington Post:
"This might be the most controversial theory for what’s behind the rise of ISIS"
which would be better as:
"Piketty says inequality drives terrorism"
although that doesn't quite replace reading the article, it's just a lot better than what was there.
The snippet doesn't mention the changing relationship between the FTC and FCC. Or how the senate is getting involved. The article nicely packages up all this related information and more into a narrative that is easy to read, so why not just read it?
