No idea about the OP, but in my case every contract I signed contained some clauses that prevented me from speaking or acting in any way against the companies interests, at least while I was working there; just like a sort of non-compete agreement but applied more broadly. Luckily I never had to test those clauses, but I'm sure had I done anything against them they would have destroyed me in court in no time. If I was in the OP shoes I'd leave ASAP. One day someone will let the cat out of the bag anyway (coworkers, researchers, competitors doing reverse engineering, etc) and he could lose his job anyway if the company tanks. Not to mention being related to a technical fraud.
