I don’t know if it’s censored or not, but there’s a business reason for this restriction even if there isn’t censorship. A company wants to be able to set different prices for goods in different countries depending on what price the local market will support. For example, if they set a price of $20 for the US but only $5 for China, they don’t want someone in America buying those cheap Chinese copies and importing them for sale in the US.
