Countries can enforce laws on American companies. See: X and Starlink in Brazil. You can pursue companies economically, you can use technical countermeasures preventing them from operating in your jurisdiction, and you can use the legal system if their owners, directors, or employees enter any jurisdiction your reach extends to.

That's all very much for this specific scenario, but the tools exist to enforce laws, if the laws exist. Being a fanatic is not a requirement for any idea in this comment.
