He's saying the App Store should be held to a different standard because it is the ONLY store for iPhones. That isn't true for the Epic store - you can just install one of the other stores, or purchase from a different method.
Apple keeps you from doing that.
I agree with you that I wish they would allow it. I agree that I should be able to put windows 10 on my iPhone. Thanks for the back and forth, and we may not be able to get past our starting assumptions about the nature of trade/commerce, but I still wouldn’t want to legally force apple to do anything. People should definitely make a big stink about it, though. Thanks for the back and forth, but I’ll leave it there.
