"In a nutshell: DRM's sole purpose is to maximize revenues by minimizing your rights and selling them back to you.
If we believe Ronald Grover's sources in his BusinessWeek article of last week, the problem is liberal DRM and not piracy, and this is a startling admission. According to him, an unnamed studio executive said that a major reason why studios weren't jumping on board with the iTunes Store and other similar services is that their DRM is too lax. "[Apple's] user rules just scare the heck out of us." It's not piracy that's the concern, it's their ability to control how you use the content you purchase."

drm was never about piracy, its about content control. they don't care about pirates, they just want to get your money in perpetuity, forcing you to buy and rebuy the same content over and over. without drm you actually own the book and can shift it to other devices and share it for the rest of your life, they dont make any money off of that.
im sure im not saying anything new but its time to drop the spin and call a spade a spade. they want you to pay and keep paying every step of the way.
