De-clickbaiting the title is IMO a good thing, it's similar to what the YouTube extension DeArrow does, crowdsourcing more accurate and non-clickbait titles and thumbnails. It's made by the people who made SponsorBlock and it's great.
Oh wow, I've never seen a paid browser plugin before. It's interesting how the idea of paying what to me is a negligible amount of money still changes the way I think about it.
The problem here is that the HN title is incorrect for this article. I'd say a clickbait title matching the submisison is much better than an incorrect title.
