Two things of note: 1) This isn't a result of US law changing. This is a result of Blizzard responding to an already-existing law which probably wasn't intended to have this particular effect. 2) Blizzard could potentially do some real good for the world (and get some good PR in the process.) I hope they have some sort of maneuver up their sleeve other than just cutting off Iranian players.
