“Friday’s news combines several different strands of politics, policy, and realpolitik: legitimate concerns about China’s ability to exert influence in the US via consumer technology; American electoral politics; and links between US tech executives and investors with the White House. But the top line is straightforward: The Trump administration gets to say it is getting tough with China by moving to shut down one important Chinese-owned app in the US — while keeping another important Chinese-owned app, with ties to Trump supporters, running through the fall.” Trump moves to shut down WeChat in the US. But TikTok will live until after the election. (I have only one thing in common with Donald Trump: We’ve both been threatening to shut off Tik Tok for months and neither of us ever actually will.)
