CCME: tis true, sometimes they walk away. other times, they keep coming (see CHBT and Citron). this case feels different, however. given all the coverage, i think china fraud allegations have come to a head with CCME, and there will be more battling ahead. Additionally, probability of a response is much higher when you're being attacked from 3 different enemies.
take a moment and put yourself in MW, Citron, or Bronte's shoes. would you give up at this point, when your reputation, your business, and potential litigation is on the line? i sure wouldnt--i would go down fighting.
