not an american, but don't forget that america strives on democracy, which means approx the same laws for everyone.

killing tiktok because it's too successful will undermine US credibility as a fair entity in any kind of business negociation, with any country.

I wouldn't be surprised if this case would be used later by the EU in regulating FAANGs even more and inventing taxes just for them ( which, as a european i find completely outrageous, for the same reasons).
