We've all seen the studies trumpeting massive losses to the US economy from piracy. One famous figure, used literally for decades by rightsholders and the government, said that 750,000 jobs and up to $250 billion a year could be lost in the US economy thanks to IP infringement. A couple years ago, we thoroughly debunked that figure. For years, Business Software Alliance reports on software piracy assumed that each illicit copy was a lost sale. And the MPAA's own commissioned study on movie piracy turned out to overstate collegiate downloading by a factor of three.Can we trust any of these claims about piracy?
