"We live in a world with "free" content, and this freedom is not an imperfection. We listen to the radio without paying for the songs we hear; we hear friends humming tunes that they have not licensed. We tell jokes that reference movie plots without the permission of the directors. We read our children books, borrowed from a library, without paying the original copyright holder for the performance rights. The fact that content at a particular time may be free tells us nothing about whether using that content is theft. Similarly, in arguing for increasing content owners' control over content users, it's not sufficient to say "They didn't pay for this use."
