are you saying that a developer should only be able to sell one copy? should films only have to sell one ticket?

Think of it as a tip, then, or even a suggested donation when entering a museum or gallery. Maybe it's not literally stealing to opt out of the agreed-upon price, but it's still a dick move. Unless you want to become an old-school patron and pay devs a salary with room and board out of your own pocket in exchange for games that you freely share with everyone. Because that's the alternative to players sharing the cost of the work and time.
