I think Valve is not some kind of God who free the human from the hand of Microsoft, they are a private company, they are just protecting their business and protecting their business "accidentally" also protecting the customer's benefits. The movement towards Linux benefits Valve the most since they have invested on Linux Gaming for 10 years now and that movement "conveniently" benefits the gamers too. That's a win-win situation, users can escape themself from a bloated Windows and Valve has the pioneering advantage.
