With TikTok's future in the U.S. in the hands of the Supreme Court, a Chinese app called RedNote is topping the charts. Yesterday, RedNote was the top free-to-download app on the Apple App Store. The Shanghai-based Chinese-language social media app has been called "China's TikTok" by users. Several TikTokers noted in videos that they joined RedNote to be petty, show lawmakers how the TikTok ban only targets that app, and to stick it to Mark Zuckerberg. Justices heard arguments last week over an impending ban of TikTok. Under a law signed last spring, ByteDance, TikTok's Chinese parent company, must sell the platform by January 19th or be banned in the United States over national security concerns.
