WSJ columnist Tony Woodlief ran into what he believed to be ridiculous demands of copyright holders and opted out of using the materials. In doing so, he endorsed Prof. Lawrence Lessig, the leading light of the Copyleft movement "on the economics".
Lessig fought the Copyright Term Extension Act at the U.S. Supreme Court. Woodlief's column shows how contemporary writers are penalized when copyright holders don't permit what ought to be fair use of the works.
