[Discussioni] opinioni su licenza BSD modificata

[Francesco Potortì]

All'interno di un grosso progetto di ricerca che prevede fra l'altro la
pubblicazione del software, uno dei partner industriali propone di usare
la seguente licenza BSD modificata.

Si tratta di una licenza BSD con l'aggiunta del testo in maiuscolo
compreso fra doppi apici.  Vorrei la vostra opinione in generale su
questa modifica e in particolare se questa licenza si possa definire di
software libero.

Io ho una mia opinione e quache dubbio, ma prima di esprimermi vorrei
sentire la vostra.
