The thing is US has its own TikToks: if US bans TikTok, CCP will use its influence to undermine FB, WhatsApp, IG, Snapchat, etc. CCP is pretty much saying: "we know you're spying on the entire world and we want to do the same; if you torpedo our secret submarine, we'll do the same to yours."
They’ve already blocked those in China, Gmail, Google, FB etc. The insidious thing with WeChat is politically sensitive items are reviewed then blocked and use of the app trains their blocking heuristics.
