Yahoo shouldn't be the one that has to filter out all traffic from France. They are, after all, a US company. If France wants to make a law (or already has a law) that prohibits what their citizens can and cannot view, make the Frech ISPs filter the content. That way, Yahoo can keep their web sites open to everyone who want to see them and has a right to see them, and the French government could enforce their law by keeping track of the French ISPs.
