Here's an excellent open letter from a blogger to Jack Valenti and Michael Eisner, in response to their push for hardware-level copy-protection-rackets mandated in all technology, and their characterization of the technology industry as pirates and thieves.
Turing's Universal Machine means that you cannot have a software or hardware protection scheme that is secure. Whatever scheme you come up with can be simulated by another computer. The computer industry are not opposing your bill because they want to encourage copying, or because they are bloody-minded, they are not opposing you because of your self serving rhetoric about rewarding artists (remember Peggy Lee, Michael?), they are opposing you because what you want is provably impossible. You can only succeed by making all Turing machines illegal.
And here's a Heinlein quote from Doc's blog that deserves re-posting:
There has grown up in the minds of certain groups in this country the notion that because a man or corporation has made a profit out of the public for a number of years, the government and the courts are charged with the duty of guaranteeing such profit in the future, even in the face of changing circumstances and contrary public interest. This strange doctrine is not supported by statute nor common law. Neither individuals nor corporations have any right to come into court and ask that the clock of history be stopped or turned back, for their private benefit.
