I foresee a long drawn out nasty international legal fight about this. In the same way the EU authorities have been very weak dealing with the car companies and emissions e.g. dieselgate, the US authorities refuse to see the problem with privacy and data. The governments are going to blame each other for stifling competition (companies from their country) etc.

I think the practices of online tracking joined up with offline tracking, as Google is now doing is going to be forbidden unless you consent.
