Bloomberg reports a group of California-based WeChat users filed a suit against Tencent Holdings, the application's parent company, over potential privacy rights violations related to account censoring. In a complaint filed to the Superior Court of California, County of Santa Clara, users allegedly had accounts frozen following comments that were potentially viewed as critical of the Chinese government. "All this chills constitutionally protected speech," wrote the users, who are joined on the suit by advocacy group Citizen Power Initiatives for China.
