You're conflating the phones themselves with the secondary markets they create.

The problem is that Apple has a monopoly in selling/distributing Apps to iphone users. This is not the case on other operating systems, technically not even on android(eg. Samsung) and has nothing to do with a "monopoly on their own products".

You're calling a product (iOS app platform) a secondary market.

A phone is a product, the iOS app platform(or app distribution on iOS to be more precise) is a (monopolized) market, not a product.
