I don't think Apple should be allowed to charge a cut from a subscription app for example. Just because I can watch Netflix on my iPhone doesn't mean it's wrong that I can download a $0 app, and then pay Netflix for the content without Apple seeing one cent from it.

But what app couldn’t be either a subscription or be unlocked via in app purchase?

The dominant ios business model for apps currently is a basic version free to download, bigger functionality unlocked via in app purchase. Up front app costs are fading.

Agreed. So the current model of “take a cut of everything” makes it very simple because they don’t need to differentiate between unlocking a full version of a game and buying a monthly subscription to music.

The first I think is obviously right the second is insane (and in between there are an infinite number of cases).

I don’t think the status quo is acceptable though.
