I used to use kindles when I was growing up, as my dad and grandpa had large amazon libraries I was able to read from. It started with the keyboard kindles up to one of the touch e-ink ones and with the exception of the last one, every one of them had the screen fail.
I have since switched to a kobo clara 2e BW, using books loaded from calibre. the price point was comfortable, with more features than I expected (waterproof, bluetooth and wifi, ability to sign directly into library accounts), I was also happy with battery life, I read on planes/trains to pass the time and had a two week long trip where I was doing a lot of traveling by train and I didn’t need to charge at all.
I plug into my computer and load books manually I also have been looking towards doing something OTA for books and page sync, libre and self hosted.
i think with fingerprinting, it provides evidence that someone touched something, not that someone did not touch it
