Sure but isn't that the definition of clickbait?

The definition of clickbait includes intention.

If anything, the poster here likely followed a rule to use the original, non-editorialized page title, and certainly the original page has not had the title set with intent to attract clicks by misrepresenting what it is.

You could write a tale in response, about how you spent seconds, minutes, hours, days, years...a lifetime identifying that the several hundred words at the link were fictional.

HN is starting to grind my tits with the amount of clickbaity articles of late.

I guess it could be. Wikipedia says the term "computer mouse" first showed up in print in 1965, but this wasn't printed until 1982.
