SOCIAL JUSTICE MEDIA: Twitter’s controversial head of China is the latest exec to leave the company.

Kathy Chen was hired seven months ago as Twitter’s managing director of Greater China based out of its Hong Kong office, but she has exited the company following restructuring in Asia. That was part of company-wide changes that included the layoff of nine percent of Twitter’s staff and the exit of a number of high-profile leaders.

Chen, who had never used Twitter before last year, was a controversial appointment when she joined Twitter in April 2016 as its first Greater China MD. Her past employment and apparent government association raised concern in China.

Recognizable names like Cisco and Microsoft apart, Quartz report that Chen previously spent seven years researching missile defense at the People’s Liberation Army and also served as CEO of a joint venture from China’s Ministry of Public Security that specialized in security and, potentially, surveillance.

Oh.
