If you want to understand data privacy in short –
1. If you give, they store.
2. if they store, they share.
3. If they share, they aggregate.
4. If they aggregate, they profile.
5. If they profile, they surveil.
6. If they surveil, they have power.
7. If they have power and you don’t, then you have no rights.
8. If you don’t have rights, then you are a slave.
9. If you are a slave, then there is no democracy.
Thus data protection is about rights protection of people from state and non-state actors and not about data.
