Help stop the renewal of the Copyright Term Extension Act

I just encountered (and signed) the rootstrikers.org petition to stop the renewal of the Copyright Term Extension Act (CTEA), making me wonder what’s up with the Act. A quick Google search landed me on this Washington Post story story with the following paragraph distillation of the current state of affairs:

The copyright extension Clinton signed will expire in five years. Copyright holders like the Disney Corp. and the Gershwin estate have a strong incentive to try to extend copyright extension yet further into the future. But with the emergence of the Internet as a political organizing tool, opponents of copyright extension will be much better prepared. The question for the coming legislative battle on copyright is who will prevail: those who would profit from continuing to lock up the great works of the 20th century, or those who believe Bugs Bunny should be as freely available for reuse as Little Red Riding Hood.
