All Americans are probably better off using Chinese apps that the Chinese government uses to snoop on them and Chinese are better off using American apps that the American govt uses to snoop on them than the opposite. The impact the Chinese government can have on an individual American is minor compared to the US govt and the same goes for the American and Chinese govts on the average Chinese person.

The Chinese government can do basically nothing with your individual personal data but if they have the personal data of tens millions of individuals then it suddenly becomes way easier to do things like influencing elections.
