A copyright law seems an odd place to start. This is computer misuse.
IIRC this was an intentional handout to media companies who were angry that ripping CDs is perfectly legal. They had to find a way to make doing the same with DVDs illegal.
I don't see a parallel here.
No it's not. There has never been a case establishing that, and it's absurd on its face. The protection measures that the law makes illegal to break must control access to a copyrighted work, and you can't copyright functionality.
