With all this money, wouldn't it make more sense to use electric trains, monorails, buses for employees to get around the campus? Who needs the pollution from all these private cars making it from one side to the other? Put in a big parking lot on each end, close the roads to auto traffic, and shuttle the people around to where they need to be. The generated good PR would be worth a big investment on MS's part, certainly better than the sketchy nonsense ad campaign they've run lately.
