Google Director René Mayrhofer Resigns Over Pentagon AI Deal for Classified Work

Summary
René Mayrhofer, Google's Android platform security director, said his resignation became "unavoidable" after the company agreed to let the Pentagon use its AI models for classified work.
A May 18 farewell note he later confirmed as authentic accused Google of losing its "moral compass," abandoning carbon-neutral goals and signing military deals he said could enable unlawful uses.
Google disclosed the Defense Department agreement in late April, saying it was proud to support national security while maintaining limits on domestic mass surveillance and autonomous weaponry without human oversight.
The dispute builds on Google's February 2025 rewrite of its AI principles, which removed 2018 restrictions against weapons and surveillance uses and has already drawn internal backlash from other employees.
Mayrhofer, who remains through August, said he will immediately stop any work tied to the Pentagon deal, underscoring wider tensions over Big Tech's expanding military AI role.
