If you believe your country would hand over any citizen to the US just because the US said so, your issue is with your country, not the US. the problem with China spying on the west through TikTok is that they can use that information to manipulate the population without stepping foot on foreign soil. And they're already doing this with TikTok. The content Chinese users get vs the content western users get is so drastically different that they're not even the same platform. This int about extradition, it's about information and control. And while you could argue that the US uses these platforms to control other countries, and I would point out that Russia is clearly much more effective at using them, and they don't even own them.
