A senior Zoom employee falsely accused users of supporting terrorism and distributing child sexual abuse material in an effort to stop them from talking about the Tiananmen Square massacre, according to the U.S. Department of Justice. In a lengthy criminal complaint, the DOJ details how the employee, Xinjiang Jin, worked to spy on and censor Zoom users across the globe.

Zoom's security woes have led to a number of organizations, companies, and schools banning or restricting its use, with some recommending alternatives such as Microsoft Teams. Video conferencing app Zoom has had a massive increase in users because of new remote work requirements due to the COVID-19 pandemic.
