This company is a problem because it's controlled by an American intelligence agency. The owners knew that was a problem, of course, and went to great lengths to hide that fact. Note that Crypto AG appeared to be a Swiss company, not an American one.
Typical American companies aren't controlled by the CIA or other government agencies.
Typical Chinese companies are substantially controlled by the Chinese government.
It's a rather important difference when trying to figure out the risks of how much you can trust who you work with. There's subterfuge, of course, so there aren't hard and simple rules. This is an exercise in risk management.
It's a rather large mistake to conclude Chinese Owned == American Owned.
