Lots of people complain about DRM as intrusive and annoying. At least it is clear what its purpose is: that is, to be intrusive and annoying.
So we have bought Season 1 of Arrested Development on DVD (it is excellent by the way). And every evening we watch an episode. Because the DVD player is used for other things, that means that it is loaded every night. And what do we have to sit through every single night? An ad warning us that downloading movies off the Internet is illegal and wrong.
So let me see. We buy a DVD. We get bombarded with an ad that is clearly unnecessary given that we bought the DVD. If we had downloaded this both would have been avoided! And so the copyright folks wonder why they are hated and I am reminded every night that I was some sort of idiot for having bought this. Terrific.
