I have no idea about this.. but I can speculate that maintaining the DRM system indefinitely after the initial sale represents an ongoing cost whose net present value needs to be considered in contrast with a DRM-free book.
- tjoff 14y agoThe DRM system is completely decentralized and doesn't cost anything to uphold.
- j_s 14y agoHello! I am unfamiliar with the details of the Kindle DRM implementation. Would you mind explaining at least the degree to which you are familiar with it, if not providing some background and/or links so that I can verify this statement for myself instead of just taking your word for it? Thanks!
- tjoff 14y ago(I haven't borrowed any e-books from amazon so maybe they have a different scheme for those) It has to be decentralized because you don't have to connect your kindle to amazon at any point in order to purchase and read a book. You can choose to download the book manually from amazon when purchasing and move the file directly to the kindle over USB and be done. The book is encrypted with your device serial number (or something similar), which is also why, if you would want to strip the DRM from the file (which might be illegal, depending on where you live), you have to supply your kindle serial number to be able to decrypt it.
