"They stand to benefit from it" how!? The only thing they'll get is immediate geopolitical scorn which could very well escalate to mass military action considering how much TSMC now means for the world's economy. A single temporary shutdown of the fabs would mean a global economic apocalypse. They'd be inviting all powers of the world to attack them for no upside whatsoever, because it will all be over by the time they figure out how to leverage the fabs themselves.
