Есть мертвый форк дебиана - vyatta os. Есть коммерческий форк vyatta os - edgeos.
В каталоге /opt/ расположена программа на perl, представляющая из себя cli и web интерфейсы. Код, который пришел из vyatta идёт под лицензией GPLv2 (без всяких лезеров). Среди этого кода встрчаются perl файлы вот с такой забавной лицензией:

Я так понимаю этой лицензией можно подтереться, выдрать логотипы и названия и спокойно сделать форк?
