In another recent episode, Creation Science Evangelism Ministries has been sending takedown notices to YouTube over a group called Rational Response Squad of posting their copyrighted material. The fact that the group's site explicitly gives permission for anyone to copy and distribute the videos as long as they don't charge for them isn't a factor, because no proof is required for a DMCA takedown notice. Proof is only necessary if you want to defend yourself against such a claim.
Although the practices in both cases are actually violations of the DMCA, with no government oversight for takedown notices it's up to injured parties to make sure the law isn't abused. For most individuals such a lawsuit is prohibitively expensive and time consuming, making it easy for abuses to go unchecked.
In an age where intellectual property issues primarily revolve around technology, we can't afford to have copyright officials who are technologically illiterate. If you don't understand how technology works, how can you be expected to grasp the implications of copyright law?
