It is a common knowledge that Apple Company really has issues with implementing/publishing third party applications from companies they might not find profitable to their sight. Since you've just boomed in their platform, they know that they can either stop you from making profits on their platform just by banning your application, or they could just sue you for things that they claim written in their TOS. Your experience reminds me on why Apple also banned Flappy Bird for the same money reasons. This really defines the fact that Apple's platform really isn't business/developers friendly.

Just a normal and bad merchant, once a fisher got a lot of fishes, the merchant tends to do everything to get the fishers fishes or make money from him.
