I think they will find a way. The Mac App Store is far from a monopoly yet it still remains profitable as far as I know.
My grandma isn't going to use any alternative store, she probably doesn't even understand the concept of different app stores. I think Apple will be fine, at least until competitors somehow gain a MASSIVE usability advantage.
