Just listened again to Jono Bacon's awesome song "Unite", which features a clip of Charlie Chaplin's speech from "The Great Dictator". Jono notes that the song uses this clip from The Great Dictator, which was released in 1940, and likely very much under the wiles of those who would like to ensure it never reaches the public domain.
This got me thinking:
Movie Studios and Record Companies are scared of letting their work go into the public domain because they're afraid their golden years are long behind them.
Fear is a great motivator to do the wrong thing. Maybe by removing the fear we can move back to doing what's right.
