@hermes: Yes it is....Is something not being shown that can be shown elsewhere? Is it being censored to avoid offending people? It's censorship!
It's not the worst censorship ever but it's certainly stupid!
Imagine I'd be going around the GB forums insulting and doxxing you, while at the same time sharing links to piracy sites where people can download games for free.
In response to that i would get my account banned and my comments removed/edited. Ain't that also censorship? If not: Why not?!
And do you realize the hypocrisy of complaining about "censorship" on private marketplaces, like iTunes, while at the same time fighting sites, like The Pirate Bay, for their "lack of censorship"?
iTunes is a "walled garden" for a reason, just like XBL and PSN are walled gardens, if you want to offer your content inside these gardens, you gotta abide by their rules. If you don't want to abide by these rules, you can always self-publish, but you won't be reaching the markets inside those walled gardens.
If you consider that "censorship" then i have really difficult news for you: Censorship is everywhere!
pornography: Sexually explicit pictures, writing, or other material whose primary purpose is to cause sexual arousal.
Apple doesn't know what pornography is.
And what is exactly "sexually explicit"?! You do realize this ain't as clear cut as you make it sound to be? On German TV we have ads that would easily qualify as "pornography" to many bible-humping US Americans who can't even stand the sight of a female nipple.
Heck there's even a pretty famous case on the United States Supreme Court regarding this issue, coining the famous phrase "I know it when I see it".
