Sure, but it would be entirely possible for Appstores to make their terms less restrictive, I don't blame people for using licenses like the GPL which are designed to push people in that direction.
I don't think it's very likely app stores will change their terms in the direction of complying with the GPL.
I don't blame people using the GPL either (except possibly people that use it for libraries), nor people that publish apps on the various stores, I was just clarifying a point.
