I don't I buy that argument without data to back it up. I'd hypothesize that the amount of piracy a title gets is directly proportional to its popularity.

Sure with an indie title you have fans that are more sympathetic to the producer, but with mass market titles you have the entire mass-market demographic. Do you really think that the number of people in the mass-market who are too lazy, dumb, or otherwise choose not to pirate out-weigh the ratio that sympathize with indie producers?

Show us some statistics please if you're going to make this argument.
