I'm opposed to censorship of any kind, especially by government. But it's plain common sense that producers should target their product with some kind of sensitivity.
Printing currency for foreigners to buy is the best racket a government can get into.
Imagine the uproar if the Federal government tried to make everyone wear a radio transmitter around their neck so we can keep track of their movements. But people happily carry their cell phones in their purses and pockets.
