If China wants to implement censorship, it has to ban all these websites that are essential for its economic development. Censorship is always possible. You can make it more expensive, but the censoring regime could just decide to bear the cost. The PRC government may decide that China has developed enough that they no longer need to provide any access to the worldwide internet to their general population. They could switch the Great Firewall to default-deny mode, and only whitelist the minimum number of services they need to keep their economy running. I think that list is much smaller than a lot of people would assume, given the domestic coercive power of the Chinese state and willingness of foreign businesses to bend to its rules.
