ByteDance, the app's parent company, has to make a deal with an American company to run their app in the US. They have until December 4th to do so. If they don't, Charli D'Amelio can kiss her one-year 100 million followers goodbye. Plus, Tik Tok can kiss the 131 million American users goodbye. They were supposed to be banned in September, but have managed to extend the deadline for a few months. But now, it seems this is their last chance. And the companies they're looking for (such as Oracle and Walmart) are playing hard. If anything, they'll keep finding ways to delay the deadline until Biden gets in office.
