A group of activists are hoping to appeal a U.S. judge's ruling that treated the censorship on Chinese search engine Baidu as free speech. In making the ruling, District Judge Jesse Furman equated the censorship to a newspaper exercising its editorial right to publish what it wants. But Stephen Preziosi, lawyer for the eight pro-democracy activists, said in an email Saturday that the comparison was wrong, and that the court had a "fundamental misunderstanding" of how search engines work.
