Libgen. If you mean legally obtaining the books you want to read, there's also the use case of home-made/unofficial copies; there are e-books floating around of books that are no longer in print (digital or dead tree versions). You'll pry my Animorphs ebooks from my cold, dead hands! There are also certain use cases where stripping DRM is allowed by law, and in those cases, yes, you would want FOSS hardware and software.
