I'd argue that the consolidation of the chip industry in Taiwan has had the most impact here. If/When China does move to take over Taiwan the global chip supply will be devastated and countries are well in their right to want to diversify from that. If anything, POTUS statements just also solidified the point that like Taiwan, they should not rely on USA or any other country for that matter. Hence why so many countries are pushing for some level of self sustainment.
Chip fabs are a red herring. They haven't been controlled by the US, and give the US no leverage over nations that used to be unequivocal allies. Those places are where technology sovereignty is a hot button issue. They can't count on the US, or US technology companies. You say Taiwan shouldn't rely on the US. But of all places where technology sovereignty is at issue, Taiwan has the least risk of being traded away in a corrupt real estate deal.
