....unless they can prove its not copyrighted
"No one wants companies to block everything unless they can prove its not copyrighted because that would remove one of the great things about the internet"
that is exactly what those big movie/music etc. companies want. whole copyright system is bs... why somebody who has been dead for ages still have copyright. copyright should care for artist during his life(and, maybe, relatives for some time after) not immortal(and immoral) companies. its same with patents.
