I think the big question is, what if this makes Trump more mad, so instead of hitting us with a 10% tariff, he blocks everyone in our government, civil service, and local governments from being able to access any US-hosted cloud services like Microsoft email accounts, Microsoft Office 365 services, Gmail, or Google Docs - before the transition to home-grown sovereign services is complete?
Sure, it might speed up the transition - if the government keeps functioning long enough to get there.
