Summing up, these are his arguments:
1. Deciding to sensor search results for the citizens of China that use Google.cn was a hard decision that management at Google struggled with for over a year. 2. There are strong business incentives that could not be ignored. 3. They hope that by making information available even in censored form it will eventually lead to change in China that will be for the better.
So in other words, the end justifies the means?
First of all there are already Chinese search engines that provide censored search. So, the presence of Google is not going to contribute to change in China any more than the services the Chinese government already allows. This just boils down to Google throwing out their mantra, "Do no evil", the first time it is in conflict with market opportunities.
