In this case it really does just sound like "the tax incentive is working as intended".

Good! Government is far less efficient anyway. How many different agencies and special interest groups does the money now not have to touch to get to where Zuck thinks it's best used? The government would just buy a few more F35s or funnel it to bail out companies like GM. Or squander it on 'investments' such as Solydra or market-distorting Ethanol subsidies. It certainly wouldn't get funneled into meaningful education reform or lowering taxes for the rest of us.
