The basic impetus behind DRM is obvious: a frantic, misguided desire to make digital products behave like physical ones. But the truth is DRM goes far, far beyond that, restricting all sorts of activities that are intrinsic to the idea of "owning" something. Two people who have thought a lot about this are law professors Aaron Perzanowski and Jason Schultz, authors of the new book The End Of Ownership. This week, Aaron and Jason join the podcast to discuss the book and the worrying status of DRM today.
