> If you live in the US, someone like Musk is going to have a greater influence on your life than the Chinese government and I see no reason to trust him any more or less than the Chinese government. So any discussion of this being a matter of national security just rings hollow.

Just because Musk is a f*ing problem for all Americans, doesn't mean that the CCP isn't a problem. Not much you can do about "President" Musk -- so you have to work with what you can control.
