HN is heavily moderated. Try turning on showdead in your profile and reading the trash that dang and co. delete from here. I doubt you'll come away with the conclusion that it should all be left up.
This includes things like removing duplicate links and changing upvoted stories from tertiary sources to primary ones. Is it "censorship?" Yes. Does it make the site better? Yes.
And yet somehow you found this site, where you claimed the uncensored internet was a fantasy.
