Because according to this definition what an editor at a newspaper engages in is censorship - and no one takes issue with that. It is an self evidently reasonable position to like or even love that kind of censorship – but the comment writes about it as though any endorsement of this kind of censorship were self-evidently evil, something not many people will agree with.

You can use this definition of censorship – but then also know that liking or loving censorship in certain situation is also quite reasonable. I want my censors to be fierce and awesome! I want to, after all, read a newspaper worth reading. And why not also moderate much more heavily at Reddit? Is that somehow evil? I think it would be awesome.
