Link to June 10 New York Times article, "China Faces Criticism Over New Software Censor".
Excerpt: China is facing a storm of protest at home and abroad over new regulations requiring all personal computers sold in the country to include software that can filter out pornography and other “vulgar” content from the Internet.
Industry executives, free-speech advocates and many computer users have reacted angrily to the new mandate, which gives manufacturers until July 1 to preinstall the software on millions of new machines.
I guess the Chinese market is just too big to say "screw you". And that's assuming there's some overlap between industry executives and free-speech advocates.
