The TikTok ban is worse for national security. It's trading in an imagined threat for a real threat. Though Xiaohongshu is having a cute little cultural exchange between Chinese people and Americans, there's so much more Chinese propaganda on that platform. I got recommended a few videos talking about Chinese/American wargames and how Americans were done for due to ultrasonic missiles and naval capabilities. You never see anything like that on TikTok. And the only reason Americans are exploring that platform is because of the TikTok ban.
