Why? If the prices are still cheaper than what you would pay otherwise, would you still boycott it? This isn't a novel business concept - airlines do this too with business/first class subsidizing economy - does this mean you don't fly either?
Look at it this way. When I fly business or first class I'd be subsidizing for those who can't afford a normal flight cost.
I don't think it would be right to claim whole of US can't afford paying for GMail calls while the entire world outside it can pay more to keep it free for Americans.
