Some people view the public domain with contempt. In their brief before the Supreme Court, the Nashville Songwriters Association wrote that the public domain is nothing more than "legal piracy." But it is not piracy when the law allows it; and in our constitutional system, our law requires it. Some may not like the Constitution's requirements, but that doesn't make the Constitution a pirate's charter.
As we've seen, our constitutional system requires limits on copyright as a way to assure that copyright holders do not too heavily influence the development and distribution of our culture. Yet, as Eric Eldred discovered, we have set up a system that assures that copyright terms will be repeatedly extended, and extended, and extended. We have created the perfect storm for the public domain. Copyrights have not expired, and will not expire, so long as Congress is free to be bought to extend them again.
