The thing about revenue is I wonder how much of that breaks down demographically. While I'm sure there are some anti-culture adults in the mix, the biggest motivation to pirate anything is when you're not an adult who has independent, disposable income (and in years gone by, the whole "debit Visa" thing didn't exist and meant online purchasing was basically locked off to the young) is that it's a completely viable and easier option to just bypass the people in your life who control that access (parents).

Even if your parents are willing to sometimes buy you games or software or whatever, there's got to be an element that a much easier path is just downloading it once a crack is available since you're more worried about burning that extremely finite supply of political capital then someone else's profit.
