@Lewis: try to keep the spit filled rants to a minimum
Apple devices work simply and reliably, and can be operated by almost anyone. There is no need for ad hominem attacks on users of Apple devices just because you personally don't agree with Apple's business practices and (presumably) think that Apple kit is overpriced and too restricted*.
In addition, it is up to the content provider to decide whether they want to offer subscriptions through Apple, or outside of Apple. The main content providers I use on iOS (Spotify, Sky, Kindle, The Times) don't pony up a penny to Apple in subscriptions, it is all handled externally.
Finally, it is incorrect to state that Apple 'do nothing' to get their 30%. In fact, they handle all money processing, handle all subscription and subscriber information and so on.
(FYI: Does Google get paid nothing when you click on an ad and buy the linked product? Do Ebay do auctions for free? Does PayPal do transactions for free? Some pretty crappy examples you've picked there)
* Here's a hint: lots of people (myself included) don't give a fuck that it is locked down or slightly expensive, we just wan't it to work, have plenty of apps and not crash or be reliant on the whims of an OEM like HTC or Moto for software updates.
I spend enough time fiddling around with computers already, I really don't need/want to be recompiling my phone's kernel.
