P.S. I just did as you said, searched a bit on the names cited, one of the top results for Neil Gaiman was this story about his missus : http://www.theregister.co.uk/2012/09/14/amanda_palmer_play_for_beer/
Gave me a chuckle - that's what I'm talkin' 'bout. You're citing the "not free as in beer, free as in $1.2m" crowd :

Ironically, searching for Neil Gaiman for a couple of minutes delivered a sterling example of why we need a solid copyright system I've ever seen, and a glimpse into what it would be like without it. This is what living the ORG dream does for creative industries, and according to Neil's missus, that's the future of music! Also, look at the project - no wonder these folks don't like copyright, it's all made from other people's ideas!
$1.2m! Those players need to tell her : http://www.youtube.com/watch?v=PR1LkDSgOXM
