Todd Spangler NY Digital Editor New York City is the latest government entity to prohibit the use of TikTok — the popular video entertainment app owned by China’s ByteDance — on devices owned by the city. The NYC Cyber Command, a division of the city’s Office of Technology & Innovation, said city workers must stop using TikTok effective immediately after the online security team determined that the app “posed a security threat to the city’s technical networks.” “While social media is great at connecting New Yorkers with one another and the city, we have to ensure we are always using these platforms in a secure manner,” a rep for the New York City mayor’s office said in a statement to the Verge, which first reported the ban.
