The Kindle DRM situation is really bad right now. It used to be possible to install the DeDRM plugin in Calibre and get decrypted KFX files from the Kindle for PC application. That hasn't been possible since early 2025. The pros can still break it but they aren't sharing with the rest of the class anymore.
