So, if you bought a DVD licensed by Sony, can they now legally enter your house and take your DVD?
Or can Sony have some sort of DRM that prevents the DVD from playing when Sony loses the license agreement?
I’m just trying to reconcile how digital purchases can be subject to license terms changes, while a DVD apparently can’t be.
Using tools to break the encryption for backup purposes is legal in the US, but distributing tools to do so is not legal because the tools can be used for non-backup purposes.
