Unlike the EU/Russia, though, the US is not geopolitically dependent on China for social media like the former is energy. If the US were embroiled in such a conflict with the China, the US would have no problem

a) Forcing the sale of ByteDance to a US company (remember, they almost did this during peacetime anyways, just because)

or

b) Outright blocking it and ensuring its allies do the same

Sure, either option is a Situation, but I would imagine the US threatening to effectively take over or block what is one of China's premiere/world-known tech companies is a large enough negotiating chip that it gives the US leverage, too, and at the same time ensure China does not interfere too much.
