You seem to have a misunderstanding of how US law works. Not all laws have legislatively-defined consequences for violating them. For example, consider laws against terrorism: even though terrorism is illegal, sanctioning individuals for terrorism can be done either legislatively or executively and occurs on a case-by-case basis.

Similarly here to ByteDance, which has violated American laws for years and is now experiencing the consequences of its non-compliance.

So actually, my claim is true; your understanding of US law is what is lacking here.
