The US government has had this concept for as long as there have been foreign producers of electronics, if not longer. You probably haven’t heard about it, but it has been there. Companies doing photo masks for chip lithography do exist in the US. Some of them have been bought by international parents. And those international parents jump through plenty of hoops to keep their certification for being able to continue to produce photo masks for classified military projects — only US citizens are allowed to work on those projects, they may need their own clearances, etc.... Don’t think just because SuperMicro may not have been a party to that system doesn’t mean the system in question doesn’t exist.
