Having taken law courses in multimedia, I see where all this is coming from. It might be a (very) unpopular decision, but copyright holders have every right to shut down live streams and YouTube uploads that you did not completely create. Although we may mean no harm by a simple video game review or tournament stream, we are still uploading and displaying a copyrighted work which we had no part in physically creating.
It's the same thing as TV/DVD/VHS. Ever read the FBI warnings at the beginning of video tapes? They basically state the work cannot be publicly broadcast (without permission.) Sadly, I see this bill (or some mutation of it) being passed.
