It feels like it might be some sort of crime specifically to misrepresent your product as being capable of X and sell it to people who you know will try to use it for X, when X is disallowed by the ToS of the platform. Con-artistry of a sort.
You could see that as "false advertising", but considering they link to the Apple TOS they're not really hiding everything.
And actually, merely adding features doesn't seem to be forbidden as long as the features you add are not "inconsistent with the intended and advertised purpose of the Application as submitted to the App Store"
So let's say you release a file manager and later, surprise! It's also a SNES emulator! Well, then yes, I can see that against the TOS. But if you're just making improvements to your app, I don't see a problem.
