@ElDeadKennedy Yes, it's programmed in C# (try to bootstrap mono without microsoft's proprietary software - good luck), there are no license headers in the source and there is no statement stating which files the GPLv2-only or the GPLv2-or-later, or even if it applies applies to anything - meaning there is no license and the GPLv2 in root is just to look nice, meaning that it's doubly proprietary software (proprietary software written in a proprietary language).
