It's a lot easier to switch which store you shop than what phone you use. Switching iOS to Android costs a non-trivial amount of money. There's also a lot of lock-in, migrating from apps in Apple land to Android land. Some people may have multiple Apple devices even. These people face a very high barrier to switching.

To me this is like asking someone dissatisfied with the grocery store that has a monopoly over their town to just move to another city.
