Scenario 1: China has spyware app that everybody downloads. China obtains information from spyware. Bad
Scenario 2: American app-maker makes app that everybody downloads. China buys information from app-maker. App-maker make money. Good
Scenario 3: All American companies have strong sense of Patriotism and refuse to sell information to China (haha). Hundreds of Patriotic companies make spyware apps that people install on their phones. Hundres of Patriotic companies get information. A dozen of them have inadequate cybersecurity for dealing with state-level hackers and information is obtained by China. But Patriots still made money in the process. Good
If the information is out there, it's out there. If you don't address the root issue and just the immediately visible part, you haven't solved anything at all.
