It doesn't need it, it's simply in a position where it can get it. From their perspective it's free money. It's the same situation with car manufacturers, they do this all the time. They get massive subsidies (usually in the form of permanent tax breaks) by pitting the governments of prospective factory sites against each other. (It's actually a form of the prisoner's dillema: governments would benefit in the net if no-one offered these subisdies, but the prize for defecting is just too great so someone always does.)
