That's unfair. I don't kill links to blog posts critical of YC funded companies. The reason I killed that post was that it was using an HN post to send a message to one.

It's explicitly against the site guidelines to use HN posts to send messages to YC, and has been many years. We ask anyone who has a message for us to send it by email. This is the first time anyone has used HN to try to send a message to one of the companies we've funded, but that seems close enough that it's reasonable to kill it. There was certainly nothing in the post to engage one's intellectual curiosity.
