"Cory Doctorow has written a Guardian column, 'The pirates of YouTube,' about how multinational copyright-holding companies have laid false claim to public domain videos on YouTube. The videos are posted by the nonprofit FedFlix organization, which liberates public domain government-produced videos and makes them available to the world. These videos were produced at public expense and no one can claim to own them, but multinationals from CBS to Discovery Communications have done just that, getting YouTube to place ads on the video that deliver income to their coffers. What's more, their false copyright claims could lead to the suspension of FedFlix's YouTube account under Google's rules for its copyright policing system. This system, ContentID, sets out penalties for 'repeat offenders' who generate too many copyright claims — but offers no corresponding penalties for rightsholders who make too many false claims of ownership."
