The main point I think everyone is missing is that Lucas Pope spelled out very clearly on Twitter that he consciously agreed to allow Apple to publish a build of his game without the full nudity option. He wanted his game on Apple's platform, and so he made a decision to play by their rules. He might be annoyed by these changes, but it isn't enough for him to forfeit the deal.
I don't believe it is unreasonable for Apple to have a value and commit themselves to sticking to it. If they do not want nudity in their products or anything else that represents them, then it is intolerant to accuse them of being [ahem] "Puritanical fuckers." Say what you like about the violence, the nickel and dime-ing of F2P games, or even the overload of poorly made apps littering their store - at least they are trying to achieve some degree of what they perceive to be excellence.
Nickelodeon has this standard. As do Cartoon Network and Disney's children's channels. Those corporations are marketing towards "family friendly" and children, whereas Apple is trying to appeal to as wide a demographic as possible. They are one of the biggest companies in the world, they probably know what they are doing to promote their brand as effectively as possible. You don't have to agree with how they want to manage their content, but it's not like this is ruining the game.
