How do people feel about having access to Android's source code versus not having iOS' source code? I like the idea that whilst certain features are permission-gated, my apps can pretty much do anything that Google's apps can do. Even if my apps aren't allowed to do something, I can still see how that something works. Apple keeps many APIs closer to the chest, so there are many things that their apps can do that my apps will never be allowed to do. And while theoretically this approach leads to a higher-quality API surface, Apple does tend to deprecate APIs here and there. How do the different approaches to platform openness affect other developers?
