So you want to utilize the power of the state to force a private entity to sell its products under terms that are "reasonable" to you?
Where is the limit on that sort of approach? Do you want the state to force everyone to set prices so that you can purchase everything at terms "reasonable" to you? How do we decide what is "reasonable"?
Given the existence of the Android alternative it is hard for me to support the argument that the government should mandate how Apple conducts its business. Even when I agree that Apple's policies have problems, I still don't think heavy-handed regulation by government is necessarily better.
