You may not want to be part of an ecosystem, but every business ever wants you to be in their ecosystem exclusively. If Amazon can keep your credit card on hand, it makes it easier for you to buy things from them, whether they be physical goods (how they hooked me) or digital goods (how they are trying very hard to keep me). I lobbied for a long time against DRM, and then I gave up, because I did want some of the content that was only available via DRM. I'll probably regret that the day Amazon decides to change the way their purchased movies work, or iTunes decides that it's streaming only (like Amazon is currently). But the fact is that unless I want to only consume Louis C.K. standup shows, it's really hard to not have DRM. I still buy physical media a lot of the time. I would assume Sony would still make money on the Bluray licensing, the cost is passed on to me, but then I have a copy of the movie with which to watch on any of my TVs or loan out to someone else.
