Sounds so fair, doesn't it ?
"Users must fill out a copyright removal request form, and when doing so we remind them to consider exceptions to copyright law. Anyone who believes their reuse of a video or segment is protected by fair use can file a counter-notice.”
Oh, you remind them to consider exceptions to copyright law, but then you go and file a strike against the YouTuber anyway. So, in practice, you do bugger all to keep things fair because even if the YouTuber disputes the strike, that won't keep you from piling them on and, after three, he's down for the count.
Stop trying to make it look like you're being fair, YouTube, because you are clearly not.
Fair would be a DCMA claim is made, the target is notified, the target then chooses to file a counter claim or not. If not, then the strike is counted. If a counter-claim is filed, then YouTube (not a judge) analyzes the video and determines whether the copyright holder is justified in his claim. YouTube then notifies both parties of its decision, and if there still remains a dispute, everybody goes to court.
THAT would be fair.
