Proof that someone is downloading something for free rather than paying to download something is not proof of lost revenue?
Has a -single person- said 'Don't bother getting the subscription, here, I'll send you the files?' Yes? Proof of lost revenue.
Has a -single person- said 'Why get DDI, I have bittorrent?' Proof of lost revenue.
You don't need to prove that someone who did download it would have bought it. You need to prove someone who downloaded it is using it. That's damn easy.
I wish I could live in a happy fairy world where people who download things for free pay for them each and every time, after the fact. Where piracy created profits simply because people who are willing to steal something have the moral integrity to buy it afterwards.
I'm not that naive tho, to believe that.
(As an aside tho, I have no moral objection to downloading digital versions of products you already own.)
As others have tried to make clear, the fact that someone has downloaded something illegally in no way proves that they would have paid for it otherwise. As I said; evidence, not proof.
