It is about more than that. There are legitimate uses for the hex code, such as making a backup personal copy of a HD-DVD you purchased in case the original is scratched or otherwise damaged (I have a dog with a thing for chewing on DVD boxes).
Just like a gun is protected by the Second Amendment against the left-wing wackos, the hex code should be protected by the First Amendment against RIAA, MPAA, and the congressional whores who do their bidding by passing unconstitutional laws.
Excuses for breaking copyright, huh. There are all sorts of things you can’t legally copy or propagate. If that bothers you don’t buy it.
