Nice post from 1729.com (Phillip Dorrell):
We Must Acknowledge The Costs Of CopyrightPhilip Dorrell, 22 January 2012
Copyright is often advocated based on its benefits.
But it also has costs.
It is not good enough to say: “the benefits are so great, we don’t even have to think about the costs”.
See also my “There’s No Such Thing as a Free Patent,” which makes a similar argument.
