I partially agree: you’re right that the Chinese government spying on American users is unacceptable, but you’re wrong about it being any worse than the US government doing it.
Only case would be if you work in government, but even then, it’d only be a problem if you’re using an unsecured device that also has Tiktok on it to do secret government stuff on, which would probably get you super-fired and possibly prosecuted in itself…
