As for the subsidies, the way they work is, roughly, the government offers you a certain amount of money to build an area, and if you don't, they either give you an extension or fine you or take the money back or some mixture of the three. There's also been reverse auction type approaches, where the government takes bids for people to build out to an area and awards the subsidy to the lowest bidder. It's not like the government just cuts AT&T a $10 billion check and says go forth and build broadband where you see fit. If you have a problem with how the subsidies work, then redesign them.
