No, because there are other alternatives. The App Stores in these cases aren't considered their own market segments because they rely on the purchase of device to access them. Those devices are available from a large number of providers. Don't like Apple? Get an Android phone from any number of providers. Don't like the service? Switch to another carrier. Until the law changes to a point where companies have to allow other people to dictate their platforms (which will never happen), a company can do whatever it wants so long as it doesn't prevent a competitor from spinning up their own version.
