ChatGPT Boycott Gains Momentum After OpenAI’s Pentagon Deal
OpenAI’s recent agreement with the U.S. Department of War (DoW) to integrate its artificial intelligence (AI) technology into military systems has sparked a significant backlash, leading to a surge in users switching to alternative AI platforms like Anthropic’s Claude. The controversy centers around ethical concerns regarding the use of AI in defense applications and has fueled a “Cancel ChatGPT” movement online.
User Exodus from ChatGPT
Data indicates a sharp increase in uninstalls of the ChatGPT mobile app in the U.S. On February 28, 2026, reaching a 295% increase compared to the previous day, a substantial jump from the typical 9% daily rate. Concurrently, downloads of Claude’s mobile app experienced a 37% increase on February 27, 2026, and a further 51% increase on February 28, 2026, following Anthropic’s announcement that it would not cooperate with the Pentagon.
For the first time, Claude surpassed ChatGPT in total daily downloads in the U.S. On February 28, 2026, according to data from Appfigures.
Negative App Store Ratings for ChatGPT
The negative sentiment towards OpenAI’s decision is also reflected in app store ratings. One-star ratings for ChatGPT increased by 775% on February 28, 2026, and by an additional 100% on March 1, 2026.
OpenAI and Anthropic’s Stances
OpenAI CEO Sam Altman stated that the company’s deal with the Pentagon would allow the U.S. Military to utilize its AI tools within classified systems, while emphasizing the DoW’s commitment to safety and adherence to safeguards against misuse. Altman highlighted prohibitions on domestic mass surveillance and human responsibility for the use of force, including autonomous weapon systems, as key principles agreed upon with the DoW.
In contrast, Anthropic CEO Dario Amodei announced his company’s refusal to cooperate with the DoW, citing concerns about its products being used for mass surveillance and autonomous weapons. Amodei stated that the government threatened to designate Anthropic a “supply chain risk,” a label typically reserved for U.S. Adversaries.
Deployment of ChatGPT on GenAI.mil
Despite the controversy, OpenAI for Government has announced the deployment of a custom ChatGPT on GenAI.mil, a secure platform designed to bring safety-forward AI to U.S. Defense teams.
Looking Ahead
The backlash against OpenAI demonstrates the growing ethical concerns surrounding the integration of AI into military applications. The shift towards alternative platforms like Claude suggests a demand for AI development that prioritizes safety and aligns with user values. The situation highlights the complex relationship between technological innovation, national security, and public perception.
