yeah, the way I understand it, that's the problem. people can make new and "better" ways to cheat since they know the secrets that Valve was doing to keep the cheating out.
as far as why only partial theft results in a delay, I would think it's all in what part was stolen, and I dont think Valve will want to tell us all exactly what part was stolen, otherwise you're telling the pricks that stole it exactly what they got.
although saying I completely understand how source code works would be very wrong, so, I also may be full of it.
