It's a matter of degrees. The title here still gives less information than it could have in the same amount of space, forcing more people to read the article to find out, than would otherwise have.

I don't think it's too bad. Kiosks aren't overly prevalent, so unlike particularly egregious clickbait examples (Dentists hate this one simple trick for perfect teeth, etc), I had less stake in the result.

I was still curious about the content (which is how a title is supposed to work, right?) so I clicked it anyway, and learned about a kernel parameter I wasn't aware of.

It's a good article, thanks for writing it.

I did not mean to negatively judge your post. After all the title does explain that it's about a kernel parameter, which is probably enough information; telling which specific one it is could even possibly be less estetic.
