I don't know if it's a problem or if it's even happening, but yes, it's a breech if it is as it clearly states nobody will be able to sell in a protected territory. There are a whole bunch of breeches if it becomes a problem which I don't know if it is? Simply don't sell master cases in those territories. Easiest way to stop it If it's happening.
