Nvidia is obviously a US company, but the chips themselves are manufactured in Taiwan. And of course China sees Taiwan as a rogue province, at at least treats invasion there as "on the table". While the US may decide to actively support Taiwan, at the very least a war over that will disrupt production.

Do normal people really view china as an adversary? I see this constantly being pushed by politicians and pundits but, unlike other countries in my lifetime, I don't really see that much animosity from normal folk. Expats who resent the PRC? Absolutely. Racism? Definitely. But there's not much appetite for the demonization of our largest trade partner, nor do I think people buy that we would ever want actual conflict with them—kinetic or economic (sans them doing something comically evil, of course). Genocide aside (for which there is at best sparse evidence available to westerners) most of the ways that they're supposedly our adversaries just seem like what we were brought up to see as "competition".
