I commented in the other thread, but MS has a long history of eagerly complying with crap DRM on the Windows side. They could have easily teamed with Sony and said no. And then what? They go PC exclusive? MS was an eager beaver because they want to monetize everything and this was their way of getting in on the action with Gamestop (Who's never been the enemy as this hilariously shows).
It's pretty hilarious how these three want it, because they're not stupid. They know the end game of this. Killing used doesn't bring in more money, it simply makes people incredibly risk adverse and drives the dollars to the AAAA titles. This will drive their market share numbers even higher. A bigger percentage of the same pie is what this about. The pie won't grow any.
