Powerful countries doing a show of force is nothing unusual. They know they can get away with it. If they had severely impacted github it would have sent a strong message not to do buisiness with people who circumvent the Great Firewall. It makes complete sense to me, they just failed.

On the other hand, why would anybody go to this length to frame to Chinese government? What would they try to accomplish? Obama sending a strongly worded letter to the Chinese government?
