Chinese-owned ByteDance has until Nov. 12 to divest its U.S. TikTok operations, per an executive order by President Donald Trump. TikTok, the personal video sharing site, is particularly popular with tweens and teens. In issuing the order, which also requires ByteDance to destroy all data on U.S. TikTok users, Trump said, "There is credible evidence that leads me to believe that ByteDance ... might take action that threatens to impair the national security of the United States." The question for parents, of course, is what app will teens and tweens put their energy into if TikTok goes away.
