It's not practical IMHO to move out of US owned cloud companies at this point in time. It could become so over years.

However what is mostly practical is to avoid building on their proprietary layers and stick to relatively portable tech. Just treat it like highly flexible servers / generic services provisioned through APIs. It's a battle to stop "cloud experts" from cargo culting "best practices" which invariably involve everything they can find at the extreme end of the proprietary stack.
