iOS devices are empirically not general purpose computers, since their manufacturer deliberately specifies applications’ allowed and disallowed purposes.

> shouldn’t

I’m simply describing how things are and not making judgments about how they should be. Apple treats iPhones as appliances that have allowed and disallowed purposes, and rules of the road for app distribution. Every iOS developer who makes a living on the platform knows this is the deal. Going on your blog and acting all surprised that this is the case shows that you either don’t have much experience working with the platform or didn’t do your due diligence before getting into the business.
