This doesn't seem consistent with the general Schrems II ruling (which was specifically about cross-border data transfer previously thought covered via EU-US Privacy Shield), and that AWS has specifically commented on https://aws.amazon.com/blogs/security/customer-update-aws-an... and https://aws.amazon.com/blogs/security/aws-and-eu-data-transf....
Is there a specific ruling or case that says AWS as a provider, regardless of where the actual data processing happens, is prohibited, this out that you can point me to?
