I actually wondered initially, even if CDL was legal, how are they going to enforce the actual Controlled part? What's the standard for that? Is simply not having a download button sufficient? Do you need to prevent people from right-clicking and choose "Save Image"? Or do you need to run the book through a video stream encrypted with Widevine L3 so screenshots don't work? Or heck, why not Widevine L1 which requires hardware not found on Windows because L3 will always be exploitable?
