>No one should be required to carry an attacker-controlled tracking device
What about being required to carry a your-own-government-controlled tracking device?
Because the US or Chine government can't harm me in Europe via the data they collect from me, But the EU authorities can if they want to, so naturally I fear them more if they were the ones hoovering my data.
What are the odds they're using this on-shore tech grab to implement their own domestic version of China's social credit score system, to easily get data on their own citizens who commit "wrong-think", without having to through the effort to twist the arm of US entities every time they want to do that?
Food for thought, but I do think we're living the last years of online anonymity, it's inevitable.
Tracking device might be the wrong thing to focus on. The US has other ways of messing with foreigners who depend on services provided by US companies, like suddenly cutting off those services in the case of ICC judges.
The odds are very low. It all depents on the people. So far, the European citizens are very privacy senstive. The European institutions are characterized by a huge devision of power. There is no chance that European instutitions can impose their will against a considerable majority of people. If people turn away from liberal democracy, that's another matter. But then everything is lost anyway.
