Google chief executive Sundar Pichai appeared on Capitol Hill Wednesday where he faced questions from lawmakers on a number of issues, including data privacy, misinformation, a search product being developed for China, and allegations from Republicans that the search engine giant is biased against conservative users."All of these topics -- competition, censorship, bias, and others -- point to one fundamental question that demands the nation's attention: Are America's technology companies serving as instruments of freedom—or instruments of control?" House Majority Leader Kevin McCarthy said at the outset of the hearing, which was held by the House Judiciary Committee.McCarthy added, "[T]he Free World depends on a free Internet. We need to know that Google is on the side of the Free World, and that it will provide its services free of anti-competitive behavior, political bias, and censorship."The hearing, Pichai's first before Congress, came just a few months after a different attempt to get him to Capitol Hill turned so contentious that a Senate committee featured an empty chair in his place at a hearing.The House Judiciary Committee has questioned technology executives at hearings throughout the year, most recently Twitter (TWTR) chief executive Jack Dorsey in September.Those hearings have focused primarily on whether technology companies are biased against conservative users, but have touched on other issues.  1447
