Apple should get a regulator ruling on the issue.
There are two primary complaints about Apple's market strategy, and that's exactly what it is.
1. Walled garden
This is what makes it possible for Apple to invest considerable capital from its own pocket to offer servers, hardware devices, R&D, and features and benefits other suppliers simply do not offer in a way attractive to end users as strongly as Apple. It needs to recapture and service that capital and to do so it insists that activity within its "walled garden" happen with a cut of the action on revenue. Fair.
2. Digital Rights management
This decision made possible the iPod music ecosystem and despite strong whining by many factions and interests, it proved to work in practice. The same principal as applied to other content such as movies, TV episodes, books, newspapers and other items will also work. In practice.
People making comparisons of price alone are entirely disregarding the delivery costs. Newspapers and magazines often operate on gross margins of 3-10%. Yes I said that right. 3%. That is because of the high cost of paper, printing, physical delivery of all that paper and printing, and the associated supply chain costs.
Apple made it possible to deliver the product in a different way, but the same product to the same people, and frankly more who previously did not have access due to limitations of geography of physical copies. It wants to be compensated for it.
The rights holders are now getting 70% net not 03% net!
