The Mouse That Ate The Public Domain, a good summary of the Disney-sponsored copyright extension act, and hopes for overturning it.
Seen in this light, the CTEA cannot survive. Because already existing works cannot be created anew, extension of subsisting copyrights does not "promote progress." Congress is not empowered merely to provide copyright holders with an additional boon - that is not "progress", but corporate welfare.
The linguistic convention by which works "fall" when they enter the public domain is revealing: immanent in the phrase is the notion that a work is debased when no longer copyrighted. Perhaps it is this view that allows statutes that shrink the public domain to gain widespread support.
