TikTok’s Chinese parent company, ByteDance, has vowed to challenge a proposed bill in the U.S. Congress that would force it to divest its ownership stake in the popular video-sharing app. The move sets the stage for a potential legal battle between the U.S. government and one of China’s largest tech companies. ByteDance argues that the bill violates the First Amendment rights of TikTok’s 170 million American users and has a strong chance of prevailing in court. However, a protracted legal fight could damage TikTok’s brand and lead to a loss of users and revenue.
