From The New York Times:
Sites Like Twitter Absent From Free Speech Pact
The effort by Google, Yahoo and Microsoft has failed to attract other tech companies, raising questions about its impact.
“The initiative was created in 2008 after human rights groups and politicians condemned the top Internet companies for complying with China’s restrictive laws rather than jeopardizing their business interests by challenging them. Yahoo had turned over data that led to the imprisonment of several Chinese activists. Microsoft had shut down a blogby a Chinese journalist who worked for The New York Times. Meanwhile, Google had introduced a censored search engine in China (although the company has since shut down that site).”
