The Trump administration announced Friday that WeChat and TikTok will be banned from American app stores on Sunday night, in one of the dumbest possible outcomes of an exhausting, unnecessary saga. 

Banning WeChat will cut people off from their loved ones in China, a particularly cruel move during a pandemic that all but prevents international travel. TikTok users, meanwhile, will continue to be able to use the app until November 12, but the app will be removed from the Google Play Store and Apple App Store, meaning new users will be unable to download the app, and TikTok parent company ByteDance will be unable to issue patches or updates to the app.
