Solution: bundle a license for the original with purchases of the sequel. Now it is on the market, so it can't be distributed for free. You make money off people who think they just want the original. But you also get a copy of the sequel into their hands, and they might try it and like it. True, it's not absolute freedom to sell things precisely how you want, but it seems like a pretty reasonable compromise to me.
