To argue that one case led to the abolishment of either system is as simplistic as it is to argue that online activism is capable of having influence without corresponding offline activities. While most online activity is unsuccessful at achieving results like those just described, the importance is arguably not merely in the specific cases or their consequent effects but in the way Chinese civil society has engaged online to investigate or pressure government behavior in a system without rule of law.
Richard Clayton has a great post summarising the recent paper for ENISA that he co-authored on the Internet resilience. Food for thought: Internet interconnectivity is a complex ecosystem with many interdependent layers. Its operation is governed by the collective self-interest of the Internet’s networks, but there is no central Network Operation Centre (NOC), staffed with technicians to leap into action when trouble occurs. The open and decentralised organisation that is the very essence of the ecosystem is essential to the success and resilience of the Internet.
