DRM is bad in many ways. For example, it represents an attempt to artificially recreate, in digital things, the inherent weaknesses of non-digital things that various business models are designed to exploit.
For example, some library systems for handling ebooks take an ebook out of the library’s collection after a certain number of people have checked the ebook out. This is done because paper book sellers know how many times a paper book can be checked out on average before a library needs to buy a replacement copy, due to wear and tear, and they want to make money the same way with ebooks.
A higher-level problem is that in order to ever really work, a policy like DRM requires total control of a system. And that doesn’t just mean control of an ebook file, or an ebook reader: ultimately, it means control of you.
