Indeed, China is probably the place that needs this kind of "shield" the most. But Google is already blocked there. Ideally, we should use some kind of P2P network against censorship, but such networks aren't mature enough. BUT, if you consider the other way: China's attack on western sites, then this "shield" is valuable. I remember no long ago China uses GFW to inject malicious code in some analytics javascript. Then all of a sudden millions of internet users started ddosing Github. It was probably because someone put something Chinese gov didn't like on Github. Github for some reason is not banned in China , but China was using this kind of ddos to force Github to take down the pages it didn't like.
