Just for the record, Gracenote is about as sleazy as it gets. They turned the contributions of thousands of people to an open project into a profit-making enterprise that’s being used to bludgeon the very users that did all of their work for them. The lesson here is that you should be careful about which causes you contribute your effort to. People like Craig Mundie bash the GPL, but if you’re doing something on your own time, it’s licenses like the GPL that make sure that some greedy bastard won’t take your work and try to sell it back to you.
