New antitrust committee chairwoman Sen. Amy Klobuchar has introduced sweeping legislation aimed at Congress’s favorite punching bag: “Big Tech.” While some Democrats and Republicans assert that major technology companies have done something wrong, there has actually been little agreement on what that something is.
