I agree that the world as described in the books isn't as dystopic as it used to be. Mind you, I remember in 1990, when SR1 was released, there were people showing how the pollution would destroy the world in 2000. And Shadowrun was that future. Now, Shadowrun is still today's future but the world has changed. Some call it post-cyberpunk. It might make a little more sense in some areas to the cost of flavor.
But I still think the GM has enough leeway to interpret what's said in the books in a way that will make the world as dystopic as it used to be. In my alternate Attitude book I'm trying to describe a world that is dystopic but still makes sense and doesn't clash too much with established canon.
