Censoring one site does not a blanket make. And HN already outright "censors" thousands of other sites (via blacklist) and moderates a very high number of other sites. So, you're complaining about censorship on what is likely the most popular highly curated site on the internet.
PG shared it here several years ago, but it looks like all the links in my original submission are dead. He said it was out-of-date at the time so it might be handy for someone to ask him for it again, idk.
edit: my team's last startup was an anonymous social network, ala 4chan + Facebook, so please understand that my current position was formed even after spending years of my life in the chans.
