That copyright is being used to line the pockets of those unable to either let go of antiquated business models, or devise new and innovative ways to deliver their products.
Witness that the *AA's (the main litigants in most copyright cases) seek to kill technologies they didn't think of, a la Napster, Grokster, Bittorrent, etc., simply so they can increase their revenue streams. They now salivate, *years* after the introduction of P2P and streaming, at the thought of charging "consumers" not for a show/song/episode/album, but on a per-device price for the *same content*.
Copyright is a barely sustainable concept, and then only when the original author/s of the content hold them.
When corporations get into the mix, we all get screwed.
