Although I obviously had nothing to do with Google’s decision vis-a-vis China, having only started working there for  a week, I was definitely glad to see it and it made me proud to be able to say that I work there.  Kudos to Google’s management team for having made (IMHO) the right decision.   Hopefully Yahoo and Microsoft will consider carefully what the ethical implications of their collusion and collaboration with the Chinese government’s attempt to control free speech and the human rights implications of the same.
I have my own opinion regarding the IETF’s decision to meet in Beijing, since as we’ve seen with the Search Engine industry’s attempt to accommodate the Chinese, engagement doesn’t necessarily always lead to openness and goodness.   All I can suggest is that those people who do decide to travel to that meeting be very careful about what sort of message they want to send with respect to China, as well as being very careful about protecting themselves against targetted information security attacks.
