EFF has released "The Blurred Lines Copyright Verdict Is Bad News for Music."
Here's an excerpt:
Artists evoke elements of common culture all the time, to make their point or simply to entertain by putting their own twist on what has come before. This is what makes culture a conversation and not a series of disjointed soliloquies. Copyright law, though, is dangerously disconnected with the way culture gets made, and as a result it pushes entire genres and communities to the margins, such as those that involve sampling, remix, and other adaptations. A staggering amount of such work is generated noncommercially and available online, but the broad sweep of copyright exclusivity, the risk of disproportionate statutory damages, and the uneven application of the fair use doctrine mean that such authors are typically excluded from commercial opportunities. Far from being incentivized by copyright, such authors typically create in spite of the threats posed by copyright law.
