you're right, it is a crappy practice morally. however, if you are going to give them an argument against this practice, you have to argue legal problems with them, not moral claims. Activision and Bungie don't really care how you feel as long as their numbers are strong. Instead of voicing your opinion on the forums and continuing to play the game, just don't play the game. that's really how they'll listen, if enough people have a strong resolve to stop playing.
