These aren't American companies. America's actual position is something more like this:

"If you do business in any way with any Americans at any point, regardless of who you are or where you're based, then you will be thrown in jail the moment we can get your hands on you, if you do business with anyone on this list, or with anyone who does not implement our rules either"

See how companies like ARM are being forced to stop doing business with Huawei despite not being American companies. It's massive overreach.
