Everything you've said here is answerable by anyone who is willing to read some of the posts I just linked to. Here's the link again: https://hn.algolia.com/?dateRange=all&page=0&prefix=false&qu....

HN is designed to downweight sensational-indignant stories, internet dramas, and riler-uppers, for the obvious reason that if we didn't, then they would dominate HN's frontpage like they dominate the rest of the internet. Anyone who spends time here (or has read https://news.ycombinator.com/newsguidelines.html) knows that this is not what the site is for. The vast majority of HN readers like HN for just this reason. It is not some arbitrary switch that we could just flip, if only we would stop being censoriously sinister It's essential to the operation of the site.

At the same time, we downweight such threads less when the sensational-indignant story, drama, or riler-upper happens to be about YC or a YC-related startup. Note that word less. It means we "put our thumb on the scale" in the opposite direction you're implying: to make those stories rank higher than they otherwise would.

How you get from that all the way back to the notion that we moderate HN specifically to suppress negative stories about YC strikes me as escape-artist-level logic, and citing a web page that we ourselves publish as the best (only?) supposed evidence for this is surely a bit ironic.
