Earlier quoted context omitted.
I don't think that matters - what matters is where the processing servers are. And if they are using CloudFront etc, they are sending data to the US.
But those 3 US companies all signed the safe heaven agreement, AFAIK.
In addition, the physical location of the servers do not change anything when the company operating those servers is American. They still need to comply with the CLOUD Act, even to the point of pulling data and encryption keys from servers based in the EU.
