It&#x27;s a great tool, but the problem with DRM to me is not the technical difficulty of removing it, it&#x27;s the validation of a business model predicated on denying ownership of the books by the users.<p>It&#x27;s like buying an iphone and then jailbreaking it: I&#x27;m all for it, but it does not change the reality that you have just financed apple practices to the tune of hundreds of dollars. For ebooks the sums are much smaller, and clearly compromising if there is no alternative more acceptable, but the problem remains.
