Yet it's totally fine for iTunes to have rated R movies and shows full of nudity, and music with racist epithets.
Seriously, what does "hate speech on our App Store" even mean? The App Store full of apps that encourage physical violence against the current President. What if I submitted an app that did the same for a previous President?
Nudity is not porn.
Porn is just people doing the naughty thing. Over and over. With close-ups of genitalia.
Nudity can be a stylistic device in a theater-piece or in a film.
There's lots of art from hundreds, thousands - and if you think of cave-paintings - tens of thousands of years ago that depicts naked people. Is that porn or is that art?
The line is sometime very thin - but it exists.
Same for lyrics in music.
