I don't think the ordinary public thinks twice about this - they just buy the product and never consider the implications. Apple got away with an atrocious copy protection scheme for iTunes music for years now happily junked (though I still had to pay to free the music I'd already bought because I'd forgotten to deregister old Macs when I bought new ones).

What worries me is the idea that a company like Apple will be the final arbiter in what people can and cannot consume. I don't think they will get away with that - when Android tablets appear so will a profusion of different distribution models. But Jobs certainly wants that control and he's exercising it in an appalling fashion. As I said in the original article how can he let through junk sex movies in iTunes films but block a text version of the Kama Sutra?
