Well ... you're technically correct that they haven't "required" people to get their media from iTunes. But the reality is, there aren't that many people willing to rip their own stuff in the first place, and even fewer willing to buy and keep track of an external drive to rip their stuff. It's one more obstacle people have to overcome.
I think this is a slippery slope, like how so many companies want to transition to email statements instead of paper statements. At first, it's optional, then it becomes mandatory. Within a generation or two of future Macs, they will stop including the software and drivers necessary to use DVD drives, then you WILL be forced to acquire any media from iTunes.
And that's fine for about 95% of the public that desires convenience more than quality.
so you're saying there will be no more stand alone blu ray players?
not like you need a digital copy dvd now. just input the code on a website or into itunes
