Are you talking about Québec? They did invent "courriel", if Wikipedia is right.

Now I think it is a mistake to mix the two aspect of the topic:
On one side, it is forbidden to do covert advertisement in France, be it for a French trademark or anything else. The guys on TV can't have a laptop with a well-known fruit on it's very visible back, as they can't wear a T-shirt with "Louis Vuitton" on it. Sometime it make thing a bit harder for journalists, because so many people have transformed themselves in flesh-ads. This is just a choice of the French. They prefer having less brands in their sight, and I happen to share this taste with my countrymen.
There is the other part of the topic, the "war" against English words in the supposed defence of the French language. This war can be sometime fought also by nationalists, but it is not nationalist by itself. (Or trying to maintain one's cultural asset is nationalist? Is it nationalist for Bushmen to try to keep their culture alive?)
On this part, I agree with the goal, which is to keep a French language as a strong cultural vector, but I don't agree with the means (keeping English words away).
