Just remember its not out of altruism. It's very beneficial to Valve to be able to eliminate their Windows dependency. I will say, it is good when incentives align for the benefit of the consumer.
Three ways to get someone to do something:
* make them love you
* pay them
* make them fear you
Markets incentivize behavior that would otherwise require altruism or fear.
I’ve always been curious what point is being made when people say this. Care to expand on it?
