Gebru said that Google only fired her after questioning an order that did not publish a study publicly saying that artificial intelligence that mimics language may harm marginalized people. The co-author of the paper, Mitchell, publicly criticized the company for firing Gebru and damaging the credibility of her work.

The two jointly led the moral AI team founded by Mitchell.

Google employee Alex Hanna said on Twitter that the company is conducting a “smear campaign” against Mitchell and Gebru and working closely with her. Google declined to comment on Hannah’s remarks.

Google recruited top scientists with a commitment to research freedom, but as researchers increasingly talked about the negative effects of technology and offered unrealistic views on the products of their employers, these limitations were put to the test.

Reuters exclusively reported in December that Google introduced new “sensitive topics” reviews last year to ensure that papers on topics such as the oil industry and content recommendation systems do not put the company into legal or regulatory dilemmas. Mitchell publicly expressed concern that the policy may lead to censorship.

Google reiterated to researchers in a memo and meeting on Friday that Google is working hard to improve the review of papers before publication. It also announced a new policy on Friday to handle sensitive departures and evaluate executives based on the diversity and inclusion of the team.
