I think I already explained that. But I do see your point. And to me the answer is the privilege of being on iOS. If the others don't like paying the 30% then they can get their own portable hardware devices, market them and sell their app on those. Or find another hardware device/OS that will take their apps for less then 30%.
Apple is clear on the 30% rule. It's up to the developers if they stay or go.
Sorry, but I don't see any rational explanation for why Apple should get a percentage of anything and everything that is sold from it's hardware.
And I'll stand by this:
If it does, then I still submit, that MS/Dell, MS/HP, MS/Asus, MS/Toshiba, etc., etc.; have the right to charge a percentage for everything you buy from that computer.
I will say, if this is Apple's intent with the Mac App store also, to force every single developer of every app and content provider that runs on OS X to pay them a cut, then I'll likely be running, not walking, back to Microsoft and Linux.
Edit: I take no issue with Apple having all apps approved by them, putting them all in a single location, providing all the billing, server storage space, the bandwidth to deliver those apps and their subsequent take of a cut. And on a new device that we were all aware of the policy up front.
This new rule by Apple has nothing to do with selling apps. This is in relation to the content providers. Content which Apple has allowed on our devices for some time now. And content which has helped to push the sales of the hardware to a great extent. Now, they want to charge the content providers that have helped to make the device the great seller that it is a 30% cut?
I subscribe to and/or purchase content from among the following:
Audible
Amazon
B&N
Hulu Plus
Netflix
I pay all of the above for their content, for which they have made their content available on multiple devices. Each of these have had their own storefront, billing, storage and have been providing and paying for their own bandwidth for delivery of their content for years.
Audible content, for example, has been available both on our computers and iDevices for many a year. So tell me, why all of a sudden should Apple get a cut of Audible's sales?
None of these companies have a pricing point set that allows them to give away a 30% cut, while still maintaining all their own infrastructure. Apple is not offering to take over the distribution of any of their content. For them to give away 30% means their pricing must increase. And it must increase, not only to those that use Apple devices, but across the board to every single customer they have.
Apple by this stroke is attempting to worm their way into not only making their own profits, but by taking a cut from anyone that offers digital content. And those that will be giving Apple money is anyone and everyone that uses content that is available anywhere if that content is also made available to Apple devices. Only it will be everyone that pays for it, not just those that use Apple devices.
This is the height of greediness, imho. And depending on how this all shakes out, could lead myself to become one of those irrational Apple haters.
I will be writing to all the content providers I use, just to let them know if they pull their content, I'll gladly stand behind their choice in this matter.
