In an east asian country, people live under constant surveillance: physical (cameras, face detection), financial, and online activity. If you criticize the government you lose access to everything: payments, transport, credit, job, etc.

If you were paid a lot of money, would you implement those "solutions"?

That is the importance of ethics.
