On February 27, according to ASIOS reports, more than 200 employees from Google and OpenAI recently signed an open letter formally supporting Anthropic’s position and calling for strict restrictions on the application of advanced artificial intelligence (AI) in the military and surveillance fields. This letterThe joint letter clearly opposes the use of AI technology in controversial areas such as domestic surveillance or fully automated warfare, in order to resist the relevant technical demands of the U.S. Pentagon.

As of Thursday afternoon local time, the letter had received verified signatures from more than 160 Google employees and more than 40 OpenAI employees, with some choosing to participate anonymously.The letter pointed out that the U.S. Pentagon is trying to take advantage of competition among companies and negotiate with Google and OpenAI respectively to obtain AI technology support that has been explicitly rejected by Anthropic.In response, the employees called on the management of the two companies to put aside their differences and jointly resist such requests from the military, and emphasized that the entire industry should maintain information transparency on the bottom line of technology.

The joint voice of frontline employees directly challenges the existing compliance and business decisions of technology giants.Data show that Google revoked its internal regulations banning the use of AI for weapons and surveillance in February 2025. The current focus is on whether the actions of these signatories can substantially force management to re-establish the moral red line for AI technology authorization in the face of Google, which has nearly 200,000 employees, and OpenAI, which has nearly 10,000 employees.
