Google engineers once refused to build surveillance tool for US military
In 2018, approximately 4,000 Google employees singed a petition against participation in US military's 'Project Maven', which used AI to optimise drone strikes. "Google's unique history, its motto 'Don't Be Evil', and direct reach into lives of billions of users set it apart," read petition written to CEO Sundar Pichai. Following major backlash, Google opted not to renew its contract.
