Not even getting into the CCP ties, it's always struck me as unfair that Western social media companies are banned in China, while Chinese ones have been able to compete Worldwide. In a way this gives Chinese apps an immediate advantage (as some are indirectly calling out in this comment section). If you want to reach out to someone in China, you have to use a Chinese company's app. Since social media is mostly a win…
They're not.
Bing has been in China forever.
Western platforms could always compete in China if they assent to domestic censorship laws like every Chinese platform. That's "fair" considering how onerous and costly compliance is. Western platforms simply have not invested in the necessary mass human moderation until the last few years, after confronted with the same violence that forced Chinese platforms to lock down post 2009 minority riots. Hence why Facebook and Google was open to engineering Chinese compliant versions after improving their moderation infrastructure following failed revolutions, genocides, mass shootings.
The reality is TikTok operates in US under US laws like how Bing operates in China under Chinese laws. There's nothing inherently unfair. The issue is asymmetric vulnerability due to fundamentally different governance systems. US could never leverage even western platforms operating legally in China to undermine China due to Chinese content controls - see China deleting diplomatic tweets on Chinese social media. But China can potentially leverage TikTok operating legally to undermine US. But instead of transferring TikTok to US ownership, which is merely anticompetitive, Trump decides to ban via executive action which is... upright undemocratic. That said, it's totally justifiable on security basis. But just remember China-hawks in current admin have no problem becoming the thing they wish to fight. That's what Americans should fear.
