Race to the Bottom
Their number one offender, is Yahoo!, and their offenses are listed here.
It starts with a statement of Yahoo!'s "Our Core Values":
“Our mission is to be the most essential global Internet service for consumers and businesses. How we pursue that mission is influenced by a set of core values - the standards that guide interactions with fellow Yahoos, the principles that direct how we service our customers, the ideals that drive what we do and how we do it… We are committed to winning with integrity. We know leadership is hard won and should never be taken for granted… We respect our customers above all else and never forget that they come to us by choice. We share a personal responsibility to maintain our customers' loyalty and trust.”
Then the article goes on to list Yahoo!'s heinous offenses against Human Rights--especially their own customers--amid their clamor for capital.
Michael Anti is well-known as the blogger who was censored by Microsoft, but he has this to say about Yahoo!:
After being censored by Microsoft’s MSN Spaces (details in following section on Microsoft), Chinese blogger Zhao Jing, a.k.a. Michael Anti, wrote that the Chinese people were probably still better off that Microsoft’s MSN and Google were engaged in China despite their compliance with Chinese censorship.82 However he had no such feelings for Yahoo!: “A company such as Yahoo! which gives up information is unforgivable. It would be for the good of the Chinese netizens if such a company could be shut down or get out of China forever.”83 He was even more blunt in an interview with the New York Times: “Yahoo is a sellout,” he said. “Chinese people hate Yahoo.”84 Such opinions are examples of the way in which Yahoo!’s behavior in China is viewed by Chinese intellectuals and opinion-leaders concerned with free speech issues.
