The only way for #Canada to maintain sovereignty without shifting entirely away from the #Microsoft stack, given the CLOUD Act, is for Canada to require Microsoft to spin off all Canadian operations into a non-subsidiary Canadian company—a Canadian-headquartered Microsoft Canada, with solely Canadian officers and controlling shareholders—bound to (US) Microsoft by contract, irrevocable licenses, and API keys, but with cryptographic keys for Canadian data retained solely within Canada. Otherwise, the #CloudAct can be used to make us a de-facto subsidiary of the USA.
The same goes (but with other countries substituted for Canada) the #EU, the #UK, #Australia, and every other non-US jurisdiction, and much the same for #Google, #AWS, and other US cloud providers. Multinational online service providers will need to become legally federated.
