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.
