"[iEffectively perptual extensions to the length of copyright are] not at all what the founders had in mind when they authorized Congress 'To promote the Progress of Science and useful Arts, by securing for limited Times to Authors and Inventors the exclusive Right to their respective Writings and Discoveries. ...'
"Retroactively extending the copyright on a work produced long ago cannot promote useful arts and sciences. It just enriches the copyright holder and denies access to everyone else -- which is exactly the point, if you're an industry lobbyist."
