Only one "Champagne" will survive

The story is, you have a region in France that produces one of the most popular wine in the world, wiht outstanding reputation as "the" wine for celebrations. Then you have a little town in the Vaud Region in Switzerland, that happens to have the same name. Since 1974 the town has been ordered by the WTO to cease using the word "Champagne" for the wine produced there (non-sparkling). More you can read here. The villagers have decided to go on with the fight, as they claim, their first production started already in 1657. Banning the use of the same name for "competing" products may be plausible, but what's wrong with these bakery products which are very popular in Switzerland?Why should they also change their name?
