Exercising the terms of a contract is not a crime (at least at this point in the Obama administration).
Corporations have many times chosen to default on agreements as a carefully considered decision. No one but the leftist press has ever termed those actions "immoral" as far as I know.
So? That's a moral issue.
A brief stint in jail, and the payoff may still be worth it.
Just run the numbers.
(P.S. An action being legal does not make it moral.)
