Well, just their right to do so. Still a bit late to do so. Might be because they're in trouble with their money since the Wii U blows so hard?
@AngelCam7 Yeah, YouTube is the one in the wrong here. They need to do a fair chop. Just because you step in an elevator for a few seconds, and they are playing elevator music that the content owners have specifically bought to hijack YouTube videos is not fair for the people who are making the video. 50/50 sounds right.
