It brings YouTube into compliance with the DMCA, but it goes above and beyond. It automates only takedowns -- putting content back up is a process that must be manually done by a user. There's seemingly no human presence you can reach out to as an uploader. There's no way for a user to upload content and explicitly flag it as "I own this, if anyone claims copyright on it they're wrong" (see NASA having their own landing footage taken down by an overly-zealous Content ID match). There's no way for someone to upload a work as royalty-free or public domain (I've heard horror stories about that more than a handful of times).

Add to this YouTube's poor view of fair use (they've come under fire in the past for misrepresenting fair use in a copyright education video), and it's a recipe for disaster.
