Your devices must work in your interests and your interests alone.
When a feature can be built so that algorithms and data are kept exclusively on the person’s own device, it must be built that way.
If a feature cannot be built in this manner, all data must be end-to-end encrypted and the owner of the device must be the exclusive holder of the private key.
The hardware, software, and services must be free as in freedom.
