YouTube's Content ID Disputes Are Judged by the Accuser
The problem is that media companies and scammers are using Content ID as an end run around the DMCA.
With the DMCA, the process works like this. A rightsholder could file a claim against a video with YouTube, and YouTube would immediately take the video offline. If there was a mistake, the uploader could file a counter-notice. The video would then be restored by YouTube within 10-14 business days of the counter-notice, unless it went to court.
It wasn't perfect, by any means, but it was fair. Disputes could always be appealed, and both parties were given equal power. And if a claimant lied about owning the copyright to the material in question, they could face perjury charges.
The current system, led by Content ID, tips the balance far in favor of the claimant.
