Explain to me what language has to do with the great firewall. Are you implying that if I switch my iPhone keyboard to Mandarin, my speech will automatically get censored by the firewall?
This is too obvious to explain. The language is spoken by 1.5 billion people who are behind the firewall and why would i have to create a content in that language when i have the option to create the content in English which most democratic country population is literate of.
