The government is made up of people. After living in China for a while, you soon find some Chinese people are friendly to your face, but are monitoring your emails thru your ISP, or tracking your movements around the city, or arranging for a breakin at your apartment. And these are young Chinese, just doing what their seniors showed them. Young Chinese don't have the concept in their minds that internet blocking harms innovation, and will do the same in government when they replace their elders.
