“Fair use is not a law. There's nothing in law.”

OSCON 2002
Context: Here's a simple copyright lesson: Law regulates copies. What's that mean? Well, before the Internet, think of this as a world of all possible uses of a copyrighted work. Most of them are unregulated. Talking about fair use, this is not fair use; this is unregulated use. To read is not a fair use; it's an unregulated use. To give it to someone is not a fair use; it's unregulated. To sell it, to sleep on top of it, to do any of these things with this text is unregulated. Now, in the center of this unregulated use, there is a small bit of stuff regulated by the copyright law; for example, publishing the book — that's regulated. And then within this small range of things regulated by copyright law, there's this tiny band before the Internet of stuff we call fair use: Uses that otherwise would be regulated but that the law says you can engage in without the permission of anybody else. For example, quoting a text in another text — that's a copy, but it's a still fair use. That means the world was divided into three camps, not two: Unregulated uses, regulated uses that were fair use, and the quintessential copyright world. Three categories.
Enter the Internet. Every act is a copy, which means all of these unregulated uses disappear. Presumptively, everything you do on your machine on the network is a regulated use. And now it forces us into this tiny little category of arguing about, "What about the fair uses? What about the fair uses?" I will say the word: To hell with the fair uses. What about the unregulated uses we had of culture before this massive expansion of control?
