@jjoelson @matthewstoller We in fact have antitrust laws strong enough to permit courts and regulators to act as DMA-style referees, and ensure firms act in ways that allow and encourage competition while they create value. Until the 1970s, firms in the US understood that even narrowly procompetitive actions that threatened competition in the longer term (a big firm competing aggressively in a new local market) would draw scrutiny. 2/
