I'm not sure how this is a reply to my comment. What you said applies whether you are hosting 1 video a month or 1,000,000 videos a month. My point was that scale isn't an excuse. What applies to large applies to small and vice versa.
The point is that regardless of the size of the company, copyright is such a shitshow that there are only less bad ways of handling it. The only way for a company to guarantee that they never violate copyright law is to do a takedown every time there is a complaint.
Obviously, this is not something they can do, because offering random people the ability to take down random videos with only the courts as recourse would be a disaster. Neither do these companies want to be in the business of deciding if a complaint is valid or not, because if they decide one way and then a judge decides the other, they get screwed.
Google tries to take a measured stance and evaluate complaints for obvious issues, but otherwise they do generally just act on them, and if the other parties involved can't agree on whether or not there is infringement, they just throw their hands up and tell them to take it to court.
Copyright is so complicated and fraught that it's virtually impossible to manage it in a way that satisfies everyone, regardless of how big or small a player is.
