Watch what happens with WeChat. Microsoft acquisition of TikTok is not barred and would allow company to avoid issues. Impossible with WeChat, a wholly Chinese company with small U.S. market. https://twitter.com/nytimes/status/1291559067631067139

TikTok is primarily a content platform, like YouTube. WeChat is social media, messaging, payments, and more.

TikTok has a primarily international market (not China market). WeChat has a primarily Chinese market, with mostly diaspora users abroad.

As many have noted, TikTok and WeChat collect a lot of data—but not significantly more or different data than American tech companies. The key difference for privacy lies in government access to data. The question isn’t so much which company you trust, but which government.

Cutting off apps due simply to national origin will change the future of the global internet. We may be moving towards a Splinternet where different countries have access to different networks. This will impact all of us, as @AnupamChander noted: https://www.washingtonpost.com/opinions/2020/08/04/trump-grants-tiktok-reprieve-his-ban-threat-should-be-permanently-retired
