> Most of them were probably manufactured in Asia just for american companies.
Again, do you have an actual source for this?

Here is TI fab map https://www.ti.com/content/dam/ticom/images/themes/facilitie... https://www.ti.com/about-ti/company/ti-at-a-glance.html for example
Onsemi have a bunch of locations everywhere https://www.onsemi.com/company/about-onsemi/locations
Hemisphere and ublox aren't even making chips in first place, they are making modules out of other people's chips
Now of course company having factory in china (or just buying capacity there) doesn't mean that particular chip was made in china but article doesn't really give much details about the chips aside from shitty picture of one (that is just generic MCU with some DSP IIRC)
Also nothing here really looks like something irreplaceable. A bunch of compute[1], the standard supporting chips (power, sensor interfaces etc.), I think only thing that might be problematic to replace are some high end analog stuff. The microcontroller on the photo
Point being they could probably get by just with chinese chips, just picked the "vanilla option" because it's easier to read datasheet in english than in chinese.
About only thing that would be hard to get off top of my head would be fast thermal cameras, as US for the long time limits anything consumer/export to low framerate and I'm not sure whether china does any of their own that are available.
> Also discovered were components built by International Rectifier – now owned by the German company Infineon – and the Swiss company U-Blox.
I'm guessing first one is some diodes/power transistors and such (easily replaceable) and U-blox I think just provides ready-to-go modules so less of a "part" more of a "module" made of stuff also from asia.
Point being blocking exports wouldn't exactly do much unless China also closed borders; it would be far too easy for 3rd party company to just... buy what is needed and get it in via china with other chips.
