Computers are machines for copying data. A good computer is one that copies well, quickly and cheaply. The internet is a machine for moving copies of data around. When the internet works well, it copies data quickly and cheaply.

Ideologically, this is difficult for some people to accept. If your fortune has been based on stopping people from copying information, it is an inconvenient truth indeed. If you earn your living by preventing copying, the only options are to change everything, or deny everything.
