We cannot do this now because user-hostile vendors have locked the functionality away from us. I think this is a perfect microcosm for the whole tradeoff: lock away the rest of your userspace and we might let you watch the new Batman DVD you already bought.
This choice of words perfectly captures the arrogance of these copyright corporations. Who are they to dictate how our computers work just to maintain their irrelevant business model? They're ones who should be playing by our rules, not the other way around. It makes me wish piracy was as bad as they make it out to be, to the point it kills them.
Just to be clear: I hate how movies are currently distributed.
It's not "theirs", they have only been granted a limited-time monopoly on it in order to incentivize the initial creation. If they abuse that monopoly, we (i.e. society) CAN take it away.
If only... Copyright monopolists lobbied governments to the point they extended the duration of that monopoly to multiple lifetimes. About 5 years of copyright protection is more than enough for creators to make their money back and then some but for some reason these people saw the need for it to last centuries. Copyright is functionally infinite, we'll all probably die before the works we enjoyed enter the public domain.
In effect, we've all been robbed of our public domain rights. The social contract was: we'll all pretend the creator's works are scarce for a while so they can make money, and then it will enter the public domain. These monopolists aren't really keeping up their end of the bargain so why should we keep ours? The second we stop pretending, they're done.
