Countries willing to pass on a US patent to China stop getting the chips (or, in this case, chip-making jobs, realistically, but that still hurts)
Also Taiwan doesn’t wanna help China and even if a US sanction was just an excuse to hurt China and get away with it they’d probably do it.
Edit: in this case, this chip is “foreign-produced items […] that are the direct product of U.S. technology or software”, according to the article. I feel it was implied but clarity is always good. US technology, used with permission in a Taiwanese good, and that permission could be retracted.
At one time, it was justified because news was months old and you could not know the candidates in a reasonable amount of time without traveling to DC and you couldn’t afford to do so.
So you elected some local guys you trusted to vote on your behalf, basically.
It’s a good reason to make the electoral college, but not a good reason to keep it.
