Apple’s bet is that developers comply, but that’s no sure thing. Many developers have not been shy about voicing their criticism of the new policies, which not only gives Apple a 30 percent cut of all content bought through apps but also restricts how apps can point customers toward purchases of apps. Apple, for its part, maintains that the change is to benefit consumers by providing a standard way to purchase content through apps. But the visibility of in-app purchase can potentially help boost volume of those sales, which may help make up for Apple’s cut.

It’s a tricky balancing act for developers, but the popularity of iOS as a platform may for many outweigh Apple’s 30 percent—especially when the alternative is to not be in the App Store at all.
