WHY GPL-3.0?

Sentinel CloudNode is surveillance infrastructure software meant to be
deployed on user-owned hardware at the edge (homes, offices, etc.). We chose
GPL-3.0 because:

1. **Freedom Preservation**: Ensures users always have access to source code
   for the software running on their cameras.

2. **Community Contributions**: Improvements made by others who distribute
   modified versions must be shared back to the community.

3. **Surveillance Transparency**: Users have the right to inspect, modify,
   and verify exactly what the software does with their video feeds.

4. **Device Integration**: When embedded in devices (cameras, NAS, etc.),
   GPL-3.0's anti-tivoization provisions ensure users can still modify the
   software.

5. **Patent Protection**: GPL-3.0 includes explicit patent grants, important
   for surveillance/video technology.

For commercial use cases that cannot use GPL-3.0, contact SourceBox LLC for
dual-licensing options.
