There is an enormous amount of skepticism towards the US TSMC deal in Taiwan, in the sense that Tsai Ing-wen “sold out” Taiwanese IP and top engineers due to political pressure.

And in fairness, the US does not have a strong track record wrt its overseas military shenanigans actually helping locals, to put it lightly. A lot of people in Taiwan are anti-CCP, but at the same time, not pro-US because they see the US as an untrustworthy or at least unreliable military ally.
