The United States has begun to view network platforms as an aspect of international strategy, restricting the domestic activities of some foreign platforms and restricting the export of some software and technology that could facilitate the growth of foreign competitors. At the same time, federal and state regulators have identified major domestic network platforms as targets for antitrust actions. In the near term, at least, this simultaneous drive for strategic preeminence and domestic multiplicity may push US development in conflicting directions.
