So how do we ensure that Tiktok doesn't covertly alter the algorithm to subtly include propaganda tailored to China's geopolitical interests that are detrimental to the US? Or even just propaganda tailored to enhance internal strife to weaken the country?
As a European I have to ask the very same questions about US apps and European interests. Even though I personally do not harbour strong suspicions towards the US, it's not a given that the US will always act favourably towards the EU, Europe as a whole, or any one particular EU country in the future. Especially in light of recent elections.
However, if Xi Jinping calls up Bytedance and tells them to show everyone ponies tomorrow, your tiktok feed will infact be all ponies tomorrow.
