Btw, I can fully understand the confusion aspect!
There are many different licenses out there and they all use various terminology expecting users to understand what they mean but the terms they include can be easily misunderstood.
Also it doesn't help when you have terms like "Creative Commons", some people who see that think that means the items covered by it are then free to use, alter, redistribute etc. Check here for full details of what "Creative Commons" actually means:
https://creativecommons.org/
For example here is the Creative Commons definition of "NonCommercial":
"While the Creative Commons licenses have evolved over time, the scope of permitted uses under the NonCommercial licenses has remained unchanged across all license suites. (In 4.0, there was a small adjustment to the wording of the definition which was not intended to change its scope.) The NonCommercial clause prohibits the exercise of rights granted under the NonCommercial licenses “in any manner that is primarily intended for or directed toward commercial advantage or monetary compensation.” In 2008, Creative Commons conducted a study on the meaning of NonCommercial in the online environment.
During the 4.0 process, CC took another look at the role of these licenses in general as well as the NonCommercial definition, and considered a name change to "Commercial Rights Reserved". The ultimate decision was to leave unchanged the license name and definition."
Makes my head hurt just reading it!
Been there, done that, got all the T-Shirts!
