I now expect Apple to police all content that appears on their platform. If anything that breaks copyright appreas Apple should be held responsbile. They can not hold on to whatever "common carrier" status they enjoy now and still censor people they don't like.

Maybe you don't know how the iTunes and App Stores work? Apple does "police all content" already.

You've not fully read the comments above that discussed "common carrier". HINT: it was decided that common carrier doesn't really apply in this situation.

No, more like "that's not how apple store works".

You can find fart apps where you press a button and you hear a fart. I doubt by allowing this app in Apple store, everyone all of sudden believes farts = Apple. Or that Apple affiliates themselves with nasty behavior in public, etc.

Apple manually approves every app and content item on their stores. They are legally the publisher.
