AI Giants Face Class-Action Lawsuit Over Alleged Pact to Slow Development

The complaint was filed by Charles Buist, Nick Spetsas, Cheyenne Hunt and Christine Bullock, who are suing individually and on behalf of a proposed nationwide class; Hunt is identified as a lawyer, while Buist and Spetsas are Florida attorneys.
The plaintiffs plead their antitrust theory as unlawful per se and, alternatively, under “quick-look” and rule-of-reason analyses, arguing that an agreement by rivals to reduce product quality or slow product improvements can constitute an output restriction.
Lead attorney Nicholas C. Rowley said the case seeks to prevent “private self-interested agreements among the world’s most powerful for-profit technology companies” from causing AI to “quickly spin out of human control,” while arguing that rules addressing existential risks should be established transparently by government and remain accountable to the public.
The complaint reportedly claims that paying subscribers were deprived of product improvements they had been promised as a result of the companies’ alleged agreement to slow AI development.
The lawsuit’s backdrop includes warnings from current and former AI researchers that rapid deployment without additional guardrails could pose existential risks to humanity, an argument the companies’ supporters have used to justify calls for a development slowdown.
