EDIT: I'll admit to pirating stuff in my younger, dumber days, and I regret doing so, but a lot of it I wouldn't have purchased anyway, so calling one pirated copy one lost sale is not true. I suspect they do that because they want to push the narrative that they're getting killed by piracy because they feel that makes it easier for them to get certain changes they feel would be beneficial pushed through.
