Anything cloud is government property, just like all financial data. Now, if your health data starts in state owned DBs, like say in Germany, there is a fighting chance the data will stay in Germany.

China bought so much data already, and with recent enforcement of their Cybersecurity laws, all data touching their citizens is fair game. Oracle pulled out of China, other like AWS go the route of joint ventures to continue operating.
