As much as there are legitimate reasons to go after TikTok, I can't help but feel it's not a coincidence that it gets singled out for legislation because it's the only one owned by China.
And yes, that ownership is problematic but I would argue that the others including those you've listed here are equally problematic for the safety of users.
So to answer your question: they should be too, but they likely won't, because the force behind this isn't a desire to protect users from disinformation, the desire is to protect western companies from scary Asian competition. Same reason behind us constantly propping up Detroit. Protecting people from disinformation is just an excuse.

Of course it's not a coincidence. It's not even a hidden, implicit unspoken motive, it's openly explained as the reason behind the concern! TFA explains this clearly, numerous times.
