Cedars from jwsurvey complains he got notice from YouTube and other hosting sites of the take down of a video he produced mocking the Caleb and Sofia videos. Again sparky using your own reference, the part that was copyrighted was the video, not the characters, he used the actual video from Watchtower. The video itself is what has the copyright and that is why it was taken down.
You also reference you have to be a real lawyer to understand these issues. First, the bar association and rules from state supreme court bars anyone who is not a lawyer from giving legal advice, not to comprehend what the law is. Second, courts tend to write opinions in a way for lay people to read and comprehend their discussions and decisions. It is a cornerstone of Western judicial principal for anyone to understand the law to atleast a reasonable degree.
