This claim is partially true. According to cfr.org, the U.S. government banned Tiktok from FEDERAL devices. This has not led to a ban on Tiktok on personal devices and will not. This was due to user data concerns, despite this, Tiktok is not the leading cause of data concerns, in fact, it is the U.S. data brokers that are more of a threat than Tiktok, where ANYONE can buy data from anywhere. TikTok is no more of a threat than any other platform.
