Today, Leslie Harris, President and CEO of the Center for Democracy & Technology issued the following statement in response to Google’s announcement. 
"CDT applauds Google for following through on its commitment to protect human rights and for its continued effort to enable China's people with unfiltered access to robust sources of information from all over the world. Whether the Chinese people will be able to take advantage of Google search now rests squarely with the Chinese government. If China allows access to unfiltered search, it will be a substantial win for global Internet freedom and for the Chinese people. If China blocks access, it will finally make clear to the Chinese people who is pulling the levers of censorship in the country."
