If you really want to make a difference and you have enough money short Hasbro.Since Hasbro has to listen to it shareholders, are you going to buy stock? Are you or you and your friends going to buy enough stock to make a change?
That was my first thought, too. Honestly, some of these threads...You want to reward Hasbro / WotC by driving up their stock price?
