Le licenze d'uso sono in realtà già contenute all'interno dei singoli programmi, all'interno di un file di testo; per esempio nel mio sistema la licenza e riportata, in più lingue, nella cartella
/usr/lib/openoffice/share/readme/
quella in lingua italiana in
/usr/lib/openoffice/share/readme/LICENSE_it
e incomincia così

Poi, segue la lunga descrizione della licenze usate, riporto le prime righe a titolo di esempio

File di testo come questo sono presenti per ogni programma installato, comunque si tratta, soprattutto quelli che citi, programmi molto noti, spesso usati dalla stesse forze dell'ordine italiane, quindi il problema non dovrebbe neanche porsi.
