RIAA blurb on the Supremes life sentence of the Public Domain:

"This is a decisive and important victory for creators and consumers. The Supreme Court has affirmed the importance of the copyright system and the authority of Congress to adapt it in response to evolving markets and international developments. The Court also recognized, once again, that copyright and the First Amendment are completely compatible, noting that our copyright system contains "built-in free speech safeguards."

I think it interesting that there are only creators and consumers, no corporations (who own the copyrights), no citizens, no customers (and how can you have a market without customers anyways?). Just monolithic multinationals.
