I have to admit that with Android itself there's at least an option. Even though Google tries to get developers into using the Play Services instead of the built-in android api (see their location api as an example), you're still able to run your own software. You can easily get other apks or use Amazon appstore.
With Apple, you have no proper way running an app without Apple. So it'll intriguing to see such act within a platform that is truly locked.
