DRM fails utterly

From John Siracusa’s “The once and future e-book: on reading in the digital age” (Ars Technica: 1 February 2009):

Nuances aside, the big picture remains the same: DRM for digital media distribution to consumers is a mathematically, technologically, and intellectually bankrupt exercise. It fails utterly to deliver its intended benefit: the prevention of piracy. Its disadvantages, however, are provided in full force: limiting what consumers can legally do with content they have legitimately purchased, under threat of civil penalties or criminal prosecution.
