Commercial authoritarianism?

The U.S. is expected to significantly escalate restrictions on Chinese EVs under the guise of "national security". On Monday, the Commerce Department proposed banning key Chinese software and hardware in so-called connected vehicles. The proposed ban not only affects Chinese EV makers, but also forces other major automakers to remove Chinese components from their vehicles before they can enter the U.S. Why is the U.S. effectively moving to ban Chinese components in EVs? Has the U.S. abandoned its beliefs in free trade and the free market? Is it really about "national security" or more like creeping commercial authoritarianism?
