Siemens and some other German majors claimed the NSA stole thier trade secrets related to wind turbines and gave them up some American companies. I think they claimed it was done via wire tap.

I'm not sure if this claim was ever validated but it seems wild those fairly boring companies would come out with it over nothing, whereas it is related to of the US services stated mission.

US government access to thier companies customers files has been a compliance issue in Europe for a while because it is hard to claim GDPR compliance if your vendor might be required to leak user data outside the judicial system. This is why privacy shield treaty was needed.
