Given that they have unilateral control as to what can be installed on non-jailbroken devices, that's rather a cop-out. Apple does have a complete monopoly on content that can be purchased for use with iOS devices. If you don't like B&N's policies, you can very often find another retailer with better policies, but this is not at all the case if you are looking for software compatible with iOS.

So? Accusing Apple having a monopoly on iOS contents regulation is like complaining Honda having a monopoly on Civic's engine parts (Yes, there are after-market parts, and yes, those WILL void any factory warranty). They make their own devices and they can decide however they want to regular its hardware/software/ecosystem, but they don't have a monopoly on mobile electronics so you are free to choose any alternatives. Calling a company having a monopoly over their own product is simply silly.
