That's a misunderstanding of how HN works. Upvotes don't determine everything here, because the main value of the site—intellectual curiosity—would quickly be overwhelmed if they did. Drama, gossip, and outrage routinely drive more upvotes, even among groups of smart people. So
HN is a constitutional democracy: mostly driven by upvotes, but with checks and balances to mitigate the bad effects. The HN guidelines are the constitution and moderation is one of the checks.
If you can't trust the community's votes, perhaps the voting system should be viewed as a failed experiment. I'm not being facetious.
After all, if you look at HN's front page five or six years ago, and compare it to the front page today, you'll see that HN used to be a legitimately useful tool for entrepreneurs; whereas now it is primarily a source of frivolous distractions. There's almost nothing on this site that helps entrepreneurs.
I understand that YC gets some benefits from the move to lower common denominator content; but in the long run do you all really want to be associated with a site that destroys more value than it creates? Because that is where HN is now. The true entrepreneurial community is gone. The voting is now useless.
Also, sometimes such comments get upvoted.
