As a consumer, you arguably shouldn't care. This is a fight between Apple and the App distributors, if it still makes sense for you to use Apple's payment processing then nobody should stop you. However, that doesn't mean Apple can preclude other people from competing with them. Who knows, you (the customer) might be missing out on a better experience because of a lack of market competition. If you aren't, then the App Store still exists. It really seems like a win-win to me.
