FWIW, in case it's useful to other readers: removing the DRM from a Kindle ebook is super easy using Calibre and the DeDRM plugin. You put in your Kindle's serial number into the plugin, download the ebook from Amazon, drag-n-drop into Calibre. From there you can convert it to pdf for specific formats, e.g. I use the Supernote A5X which is a great reading and annotation experience.
