The Null Device
Lawyer and copyfighter Edward Felten has come up with a Godwin's Law for copyright policy:
As a copyright policy discussion grows longer, the probability of pornography being invoked approaches one. (Corollary:) When the topic of a copyright policy discussion switches to pornography, each side suddenly adopts the other side's arguments.
For example, Hollywood argues that filesharing will lead to a shortage of movies, because nobody will make movies they can't sell. But when the topic switches to pornographic movies, suddenly they start arguing that filesharing increases the creation and availability of content.
Similarly, some P2P vendors who say they can't possibly filter or block copyrighted content, suddenly decide, when the topic switches to porn, that they can provide effective blocking.
