This is the same reasoning the music and movie industries use when they go after people downloading music. And contrary to the popular opinion, I think it is wrong: if people want to pay, they will pay. Same for movies: if people would really want to pay for a movie, they would go to a cinema. Or stream it after a week or two. But there are also people who would jump through hoops than pay for music or movies. And that is not a lost sale because there was never an intention to buy something in the first place.
