Apple, Qualcomm, Nvidia, AMD and Intel are using TSMC to produce some, most or all of their chips currently. Shutting down TSMC or controlling its allocation will hurt many countries right now.
Seeing as TSMC is currently scaling up fab production in the US with their new fabs means they’re feeling that pressure and made the deal with the promise of US protecting them.
However, seeing as the current US administration is all over the place and Nvidia started selling to China again, I wouldn’t count on US risking all out war to protect Taiwan anymore.
So the plan is to concentrate people in military camps. What a novel idea.
