If it's sold to a US company then it will be our intelligence agencies pumping the propaganda, not theirs. Which is an outcome I'm more amenable to, considering that our intelligence agencies generally have more of an interest in the stability of American society than the intelligence agencies of China.

So if it's propaganda either way, then no loss will happen?
