I don't see how their measures will help. It might have helped a few years ago, but one can literally ask to recreate the full book contents 1-to-1 with any local uncensored LLM just from a video of changing pages. You don't even need to break a DRM in a classical way.

If I were them, I would rather respect my users than fight with windmills.

That's putting a lot of trust in the LLM to avoid transcription errors, especially in books that include equations and similar complicated formatting, books in languages not well-represented in the LLM's training set, etc.

To say nothing of books with pictures.

As an alternative, why not hack the Android Kindle app to spit out bit-perfect DRM-free copies, with or without the assistance of the same LLM?
