Eight New York residents are suing China and its biggest search engine company, accusing Baidu of conspiring with the government to censor pro-democracy content...Baidu spokesman Kaiser Kuo declined to comment. According to the complaint filed in the US district court in Manhattan, Baidu acts as an "enforcer" of policies by the ruling Communist party in censoring such pro-democracy content as references to the 1989 Tiananmen Square military crackdown. This censorship suppresses the writings and videos of the plaintiffs, who are pro-democracy activists, to the extent that the materials do not appear in search results, the complaint said…"We allege a private company is acting as the arm and agent of a foreign state to suppress political speech, and permeate US borders to violate the First Amendment," Stephen Preziosi, the lawyer for the plaintiffs, said [also refers to Google, Facebook, Flickr, Twitter, YouTube]
