I haven't heard of anything like this happening before. Is Masters a required competition for French skaters? When a federation is unhappy with a skater for doing something wrong, don't they usually just fine them monetarily (i.e. Rachael Flatt for going to Worlds injured)? This hurts the FFSG's image and the French team in the long run by depriving Brian of an opportunity to compete his programs in front on international judges during the Olympic season.
Also, if they were considering this since the Masters competition, couldn't they have withdrawn him earlier so that Skate America organizers could line up an alternate with more advance notice?
