Nor does he understand the scope of Trump's 2017 CLOUD act, which expressly states any data in any datacenter that is the property of a US corporation, regardless of where it physically resides in the world, can ultimately be accessed by US statecraft, on demand.
There is no 'data sovereignty' with GAFAM. Ever.
