This means that if there is DRM on a DVD, even though it is legal to make a backup of the media you own it is illegal to bypass the DRM. There is no copyright infringement, but you have broken the law.
Yes, bypassing DRM is against the law unless you're doing so for one of the approved reasons. What content you're bypassing DRM to access is unimportant.
If I pick a lock for a safe I bought, it’s not illegal. But if I do that with software it’s illegal? Fuck that!
