No, it absolutely is not. Not even close. Love for clever little hacker things does not carry any weight here. How could you possibly believe that it would have been illegal for this company to correctly state the amount of revenue it received?
You do not need to acknowledge that you received an NSL in order to acknowledge you are no longer providing services to the NSA. You do not need to reference the NSA or NSL at all in order to correctly state revenue, because you are not required to show all of the entities with which you're doing business.
It is fully possible to pretend you simply lost the NSA contract for non-NSL related reasons. His fraud is his own doing
