How does ePUB DRM work?

Oh, I like it. Better get a tape of that commercial before they clarify it.

Murraypaul:

"Circumventing the DRM is removing/disabling/exploiting it to allow you to do something that the DRM would otherwise prevent. If you buy a book from Amazon, which has DRM allowing it to only be read by Amazon devices and apps, and you remove the DRM to allow you to read it with a different bit of hardware, then you have circumvented the DRM. "

That is quite possibly true, and frankly, I don't know if the LAW has a specified FINE (maybe torture) or if that would be for a jury to decide. So it could amount to the trespass concept where that blade of grass was damaged but the compensation is ONE DOLLAR. If the "freed" book is not given away or "torrented" then the damages might be quite minimal.

And would Amazon (or the others) be willing to trust that a reasonable judge or jury might just decide the law is unconscionable cannot be enforced. Actually, a judge would do that.
