You can argue all you want but I make my living off of copyrighted works as a programmer, webmaster and even as a photographer and you are WRONG when you say the author doesn't suffer from copying and I vigorously defend my copyrights when infringed.
And so do I so I hope YouTube gets reamed. I honestly don't understand why people cannot see that it is just plain wrong to do this. It costs me time and money to protect my website content. If copyright infringement did not exist this is one expense I would not have.
Death to the copy thieves! Off with their heads!
But seriously, I think this guy has good case and I hope he wins.
