"Reading on a E-device is a bother, I have to sift through all the "sponsored" books and whatever other crap the ebook reader company decides to add, and be at the whims of whatever they decide they want to do with "your" device that day."

My fellow, you are on Hacker News. Think like a hacker, not a consumer.

Plenty of savvy e-book customers here don't have the experience you just described. Look up how to put KOReader ( https://koreader.rocks ) on your current device, and learn how to get your books without DRM. Your e-reading experience will be so much better.
