That's not what Adam was saying. Saying something is never black isn't the same as saying it's always white. There are no absolutes other than that 1 pirate copy != 1 lost sale and not every person pirating wouldn't have paid for a pirate copy. It's somewhere in between but is quite literally impossible to quantify. There is a massive difference in releasing everything you produce as free and turning a blind eye to pirating. Turning a blind eye means that your software gets pirated, people hear about it and from that publicity and sales are generated. I've downloaded certain indie games and programs before that would allow you to bypass the registration if you wanted with nothing other than a friendly reminder that if you enjoyed the product you could pay for a full licence from their site. Which I then did. If the game/program was released for free then I would still have the same product but I wouldn't pay.
