TSMC is an independent company, not even a US one, not a government agency, what happened to free trade and no government interference with business? Microsoft has a long T&C contract that includes not selling its products to some countries, as do all semiconductor makers and if these were followed, cell phones would not be available in many countries, nor would computers, so this idea that products can be stopped from export is just a publicity stunt.
The US should stick to wrecking its own economy and not trying to control the world, TSMC should tell them to get lost. Clinton tried attacking China, so did Bush, Obama, Biden and all it does is spur those countries attacked to grow their own products.
Bullying doesn't work, it makes the rest of the world see the US can't be trusted which is why only the EU still trades with the USA as its main trading partner, the rest of the world has moved to China
