In general anything that has "algorytmic content ordering" that pushes content triggering strong emotional reactions should be banned and burned to the ground.
Aren't you describing your own comment? Aren't upvotes pushing that to the top? So isn't HN the thing that needs to be banned according to your comment?
They are qualitatively distinct. Facebooks' algorithm is demonstrably harmful. HN's not so much.

It's imperfect, but afaik most social media does the opposite (all "engagement" is good engagement), and I imagine, say, Twitter would be much nicer if it tuned its algo to not propagate posts with an unusually high view/retweet count relative to likes.
My point, overall, is that there is all the criticism of social media that excludes HN is based on vibes. And if we're about to ban social media for the EU then hopefully we have more than vibes to go off of.
