New updates to copy protection stripping tool Requiem appear to have removed the copy protection from Apple's paid iBooks downloads. The update so far is only known to work with ePubs and not Apple's newer .ibooks textbook format, but it has been tested on the MobileRead forums and elsewhere as working. The app had already worked with pre-iTunes Plus music and with at least some videos.
Electronista and MacNN don't intend to encourage stripping out copy protection and aren't linking directly to the utility.
Adding iBooks derestriction wasn't necessarily a difficult challenge, since Apple's FairPlay system is believed to be largely consistent across formats. However, it's likely to frustrate publishers that have been hoping to keep their e-books locked to individual users and devices.
Although Apple developed its own copy protection system, the company has usually been of the view that content should ideally go without copy protection at all if not required. It has usually been asked to implement digital rights management (DRM) as a term of getting business at all from publishers, movie studios, and previously music labels. [viaCNET]
