Reddit is heavily moderated too, but there you can get into an argument, and it depends on the subreddit.
Here the tone policing is far, far stricter. Also the homepage is incredibly tightly controlled, politically and pro-YC. I've seen many articles on YC companies or associated people changed, removed, etc despite being highly relevant.
Titles are changed to suit the mods tastes here. There was a good recent example where a very negative article on OpenAI skyrocketed the the top of the homepage, fastest rising post ever with a few hundred upvotes within like an hour - first the title was completely neutered, then the post was removed entirely.
The tone policing is far stricter, but the actual content policing is a lot less absurd. The result is that controversial topics and opinions don't result in as much of a toxic cesspool of name calling. On top of all that, here you can enable the display of deleted and flagged comments.

Yes, there is censorship on HN, but it's typically enacted by users instead of mods.
It's heavily censored but that's fine as it exists to serve a niche business community. And HN never claimed to be a free speech platform like reddit did.

He does that for sure, but he also censors heavily to meet the corporate, social, etc agenda.
When the admins and power mods of reddit decided censor more, HN is one of the censorship models they looked to - the psychological tricks, front running, shadow banning, etc.
I don't feel like HN is censored. Does anyone think HN is censored? dang steps in mostly with technical edits or to break up a particularly nasty fight once in a while, can this really be called censorship? of course, you can take a karma hit from other people, but reddit always had that as well.
