Funny.... Apple rejects one App for reasons that are only speculated, and everyone wants to jump to the worst conclusion so quickly based on some writers news hype.
It makes no sense that Apple would limit outside content or outside apps. They limit certain things for security reasons, but not to prohibit use or content.
Think about it people... Apple would have nothing to gain with this sort of speculated lock down... especially if they want to gain users like the person above and I'm sure they do.
Not one app. There is a newspaper over here in The Netherlands that provides a free digital version with a 'paper' subscription. This goes through their app which is rejected. It must go through the new future appstore subscription system with a 30% share for Apple. Result: no more free digital version. Who's the winner here?
