Three years ago, we warned of Big Tech’s campaign to weaponize U.S. national security to protect its monopolies from antitrust scrutiny. At the time, Google and other tech giants argued that bipartisan legislation in Congress to curb their monopoly power would harm national security. They claimed that Big Tech companies were “national champions” like Lockheed Martin and Raytheon and should be exempt from antitrust laws to protect America from foreign threats such as China. Unfortunately, many conservatives in Congress fell for this argument and the legislation failed.
