Interesting that there has been no response from Beijing yet. We're all waiting for them to add the now-unfiltered google.cn to the firewall, but doing so would be in some way accepting Google's argument - making them look weak. I guess their best option would be to make no formal response to Google's allegations, leave the site unblocked for a few weeks until everyone loses interest, and then block it on a routine batch with a load of other sites... ideally when something more important has just happened in the rest of the world.
