Not fully since I'm at work, but chargeback claims are a serious issue and I'd prefer in most cases to lose a sale, or even 10 sales, than to take a charegback claim. Now sales in my industry (household stuff, food, kitchen, garden, etc..) have a lot more variable price so it doesn't always apply.
I empathize with developers saying they'd prefer their game pirated, because it's a feeling I get in my day-to-day.
