My pessimistic opinion is that within Apple's walled garden, the consumers don't get to choose. If the majority of apps go the subscription route, they will succeed because there is no alternative. Average users won't stop paying because it's subscription; in the grand scheme of things, I suspect my refusal to go along with that model puts me in the minority.

I'm a huge fan of Apple hardware/software, but the App Store is not something I ever expect to operate on a set of ideals I agree with. The day they came out with in-app purchases, I figured the days of a model designed for someone like me will never happen.
