History

Historical Context

After the DOJ and 20 states sued Microsoft in May 1998 for bundling Internet Explorer with Windows, Judge Thomas Penfield Jackson’s 1998 findings led to a 2001 settlement that forced Microsoft to share its APIs and accept a monitoring panel. The September 18, 2024 antitrust complaint against Anthropic, OpenAI, Google and SpaceXAI echoes that precedent, seeking similar data-sharing safeguards for AI.
