universal and youtube

So universal is suing youtube over some copywrite laws which seems kind of crazy its not likely that the video's will stop on Youtube. I suppose they would or could but they will just surface some where else on the internet its wide open to stop it on wide wide web. There's so much copywrite laws broken every day is it really a law. if the news releases in the news are not breaking the law is it still breaking the law to show some thing on the internet if everyone knows that it is made by some one else. my understanding is that universal is suing becasuse their clients clips of music and what not are being shown on you tube but are the people posting them on you tube claiming them as their own. i belive universal just wants to try to get old murdock by the balls and it probably wont happen not that it would phase him anyways "pocket change" to him.
