Microsoft put all those functionality-crippling features into Vista because it wants to own the entertainment industry. This isn’t how Microsoft spins it, of course. It maintains that it has no choice, that it’s Hollywood that is demanding DRM in Windows in order to allow “premium content” — meaning, new movies that are still earning revenue — onto your computer. If Microsoft didn’t play along, it’d be relegated to second-class status as Hollywood pulled its support for the platform.
It’s all complete nonsense.
