"thinkingthing": That's not how the current distribution of NeoPwn2 works. It was released, temporarily, as a private beta. One that you paid to get into. Linux is open source. Linux is also just a Kernel. It can easily have programs for it that are neither open source nor free. This, right now, is neither. It is supposedly going to eventually be released as both free and (as I understand it) open source software. Last guy who publically announced he was making the beta available for download got his hosting revoked. Copyright does apply to this, and until it's open-sourced, it being on Linux doesn't change that. (But I'm sure you probably could find someone willing to secretly give it to you. I am not such a person, but I have no doubt some are.)
