Josh BeckmanAny software is considered free software so long as it upholds the four essential freedoms:
- The freedom to use the software for any purpose.
- The freedom to study and improve the software.
- The freedom to share the software.
- The freedom to collaborate on the software.
Software which upholds these freedoms is free software. Software which does not is non-free.
