Whether or not one is making monetary gain off of web casting or not doesn't change the fact that they are broadcasting a performance of intellectual property, one of the six exclusive rights to copyright ownership. Like, bootlegging movies would not be okay if you were giving all the money to charity, because you are still taking income away from the people who deserve it and whose property you are exploiting. Remember this income from copyrights is not just going to labels, it goes to artists as well. In fact, the only reason labels get a piece is because artists AGREE to give them a piece for services the label can provide (marketing, distro, etc). No artist is ever forced into signing to a label, its a voluntary decision for career betterment, that pretty much every artist would leap at if given the opportunity. There is a whole team that makes an artist what they are and what they accomplish, and while we love to glorify the people who write/play the music and condemn those who run the business side, both parts are equally relevant in making the music industry function. Without the industry side, we wouldn't have all the digital sound recording technology and CD and DVD technologies which I think we can all agree make music a better experience than scratchy old analog devices.
