God damnit this stuff is annoying the hell out of me.
No, not the fact that they're muting stuff. The fact that everyone, who has signed up for YouTube, and is commenting on videos saying it's not fair and they should've gotten a warning about this happening, is 100% wrong. Why? Because in the damn agreement they abided to to even get their accounts to post those stuffty videos up there in the first place, it says, quite clearly, that you cannot upload anything that does not contain content you and only you created.
It even says it, again, in the video uploader.
