I recently downloaded some source code that is licensed under CC BY-NC-ND, but contains code licensed under GPLv3 that it is dependent on. Which license am I granted the rights of?
GPLv3 states that:
You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it.
Is this software therefore effectively dual-licensed, allowing me to choose between CC BY-NC-ND or GPL, even though the author does not explicitly state such?
I understand that an error here has been made by the author of the project and that they are in fact violating the original creators GPL. But what rights do I have (as the author of neither project)?
This is made particularly more confusing for me, since the project licensed under CC BY-NC-ND actually has many public contributors, myself included.
