Not that MS hasn't always been about that, but it's clear they're doubling down on it.
They might as well play by the same rules as their competitors.
It's unfortunate for consumers, and I hope that in the long run market forces and/or regulation will open things up again. However, for the immediate future, if your major competitors are running closed worlds and you're the only guys running an open one, there's only one direction that customers can move in.
