The license can't be specific to a product in other words if I distribute my software on a Red Hat system the license can't say you can't distribute this on a SuSE or Debian system
Baimena ez da gai bati bereizia izan behar; beste hitz batzuekin, nire softwarea Red Hat sistema batean banatzen badut, baimenak ezin dezake esan: "ezin duzu softwarea hau SuSE edo Debian sistema batean banatu"
