In theory Google has a content ID system that could block the unlicensed uploads - but nobody can compel it to use the system
Huh? Is that a claim that Google is not taking down videos through Content ID?? That I remember, most of the complaints about that system is overflagging videos for content that should be in the public domain, or is not even owned by the claiming entity. I have never heard of content producers complaining that the Content ID system is not working… And God knows they know how to complain when they feel like it.
