Big Tech platforms have become an inseparable part of our daily lives—shaping how we communicate, access information, and make decisions. However, the natural monopoly dynamics of digital platform markets have concentrated immense powers in the hands of just a few private entities. For-profits have developed closed, shielded, and incompatible ecosystems that allow their owners to capture users and benefit. Positive platform externalities have allowed tipping to Big Techs that need not fear entry or rivalry. While the disciplining force of competition could foster better alternatives and greater choice, it remains constrained by structural barriers and anticompetitive practices.
