Hi!
Many people detest the TCPA guys. I don't do. They just thought logically.
There are two possibilities:
1) Make sure copyright is obeyed. Therefore you need close to perfect control over all computers and media-displaying devices of the world. Additionally, the attempt to circumvent this control has to be fined heavily by law.
2) Forget about copyright. Accept that information has the desire to be copied. (An interesting essay about this can be found in Douglas R. Hofstaedters "Metamagicum")
They acknowledged that there is no possibility in between and chose number one (surprise!).
HAND, Kevin
