I don't think it's quite "the law and personal morality" as much as it is "not my money to pay for the licenses, whereas I might get fired, pay a fine, or go to jail if I give the direction to steal the software."

In the same way, it's not my personal morality or the law that prevents me from stealing the supplies my company needs in order to help my employer cut costs or burning down the buildings of our rivals. Those things wouldn't help me personally but they expose me to lots of risk. That the law and morality agree with self interest is a happy coincidence.
