National Organization for Marriage v. Maddow [1]

According to Wired's Threat Level blog [2], in April 2009 the anti-gay-marriage group National Organization for Marriage ("NOM") [3] sent a DMCA takedown notice to YouTube, demanding that it take down a clip from MSNBC's Rachel Maddow Show [4].  In the clip, Maddow criticizes NOM's "Gathering Storm [5]" advocacy ad, displays short excerpts from the ad and 40 seconds of leaked audition outtakes from the ad [6], which had been uncovered by the Human Rights Campaign and posted widely on video-sharing sites like YouTube. 

MSNBC apparently sent a counter notice, and YouTube put the clip back up.  Subsequently, Maddow commented on the DMCA takedown request and chided NOM on the air [7] for using copyright law to silence critical commentary:

A cable news segment critical of an issue ad violates the copyright of the organization that made that ad? So you can pay to put it on TV, but I can't address its merits on TV?  Come now anti-gay-marriage people, I know your campaign is about how scared we should all be of gay marriage, but now you're scared of people talking about your stance on it?
