> Where's the law that says that an American business must sell their product or service to a foreign company?
As I understand it, it's covered by the various antitrust laws in the United States. And it's not so much a "foreign company" thing so much as it's an unfair advantage for any one company thing. https://en.wikipedia.org/wiki/United_States_antitrust_law
Again, not a lawyer. But my lay reading would say that it would feel comparable to the action the feds took against Microsoft for trying to stifle Netscape. But I'm sure there are far better analogues.
