Are those actual "pirating ebooks via the analog hole to defeat DRM?" videos?
All I see with a quick search is doing it via using a robot to turn pages in a dead tree book and taking pictures of the pages. (Although I swear I've seen a post regarding doing it for ebooks)
(Though for an ereader with buttons you could just have the robot press the button rather than flipping pages, it should be easier than the more complicated action of turning a page in a paper book)
EDIT: I was right
