I think this is rather naive. I agree that the foreign aspect is an important component but let's also recognize that TikTok's success is because they are so successful at this data collection and manipulation. There's two reasons to target TikTok specifically. 1) Foreign influence 2) they are top dog.

Let's also recognize that Uber is not collecting data on what you watch and what social activities you participate in. Google and Meta are much better examples than Uber. But Google and Meta have also not captivated the attention economy of people the same way as TikTok has. You go after the worst offenders and it is clear that TikTok is the worst offender before you include the foreign aspect.
