According to the Internet's caped crusader, Cory Doctorow, a group of American record companies is likely behind the recent astroturf effort that goes by the name Balanced Copyright for Canada. From BoingBoing:
It's really telling that the opposition to the Canadian DMCA has come from real grassroots: artist groups, citizen groups, technologists, educators, disabled-rights groups, archivists -- people who don't hide their funding or their affiliations behind false flags. Meanwhile, the only support for this law has come from slick, fraudulent PR campaigns that shroud their origins in secrecy in order to disguise the fact that this is just the same four record labels running around in circles, wearing several hats, pretending to be a crowd.
You can find more information from Canadian law professor Michael Geist.
Hat tip to Mr. Doctorow and BoingBoing.
