They don't like fair use, but it is not clear fair use protections could be legislated away without a court overturning any such clause with a first amendment argument. If that were to happen, foreign corporations could sue the US for damages, and win, but no other legal remedy would be available -- they could not stop the fair use from continuing. Maybe they could sue again the following year.
