If United States was honestly concerned about data protection and privacy, it would devise a federal privacy law that models GDPR. They are trying to pass a federal law now, but it is seriously flawed and they are trying to preempt more user-centric privacy laws of the states.
Finally, such partisan, targeted and unprincipled bans reenforce that EU's approach on issues such as data transfers abroad (see Schrems 1 and Schrems 2) is perfectly valid. EU has a principled regulation, which gets evaluated by free and democratic courts. The outcomes are what they are. Not partisan and discriminatory, as they are here.
