Great Firewalls are great failures. In China, the birthplace of the Great Firewall, the major online control strategy isn’t censorship, it’s disinformation: the Chinese politburo employs a vast cadre of trolls who rubbish anyone who talks about things the government dislikes, discrediting them and muddying the waters. In China, which has the world’s largest population of network engineers, where the majority of the world’s routing equipment is made, where the law provides for penalties up to and including having your organs given to party members — in that China, they can’t make firewalls work.
