Consider GP's position: they wrote some code for their old employer, and therefore had no copyright over it (I hate capitalism). Point is, they had very little stake, beyond personal pride and ethics. So now they see that their code has been stolen from the previous company, and they're being asked to work on it, what will they do? Refuse to use the code and risk being fired for being too slow? Report the crime and risk being accused of attempted to cover their own tracks? Talk to HR and being hated by one's closest bosses? I see no way to really win here. At least, not reliably.
