that's a great question. I had reviewed the Wikipedia page prior to my comment: https://en.wikipedia.org/wiki/Clickbait

it seems there is no universal definition of clickbait. So I based my comment on this:

1. the article was posted on Thibault's own website that doesn't generate revenue per click. Isn't clickbait associated with the possibility of additional ad revenue?

2. Thibault recently called for help on the issue. This post recaps what he went through. He clearly expressed that the code upgrade process didn't go as planned for him. the post and sub-title feels genuine.

3. Clickbait (to me at least) indicates that there's either intent on generating revenue or self-promotion. I fail to see those conditions here

So that's my logic. So why would this be considered clickbait?

Clickbait is a sensationalized or misleading title meant to draw extra attention (in the form of clicks).

Both "big upgrade" and "didn't go as planned" are technically true, but overpromise. A big upgrade could be new features, improved UI, something that affects the user experience.

"Updated Lichess language version, had to tweak cache settings" is a title that isn't trying to sell itself.
