The “licensor” is the person on Thingiverse, and they cannot revoke the rights of anybody that has used/shared/remixed their model. In other words, they have to respect the licensee when they use/share/remix the model.
As far as I can understand it is possible to put a more limiting license on a remix of the Thingiverse model with the “CC BY-NC” license.
That said, you always have to credit the source model and you are never allowed to benefit financially from any derivative that you designed. Therefore both examples breach the original license and should therefore be adapted/removed.
@KanneKaffe “You have no choice but to report it.”… I do have a choice, and that is to NOT report it. I will report anybody that steals one of my designs (happens a lot on MW sadly) and I might report designs that violate designs made by others. Most of the time MW handles quickly.
In this case though, since I publicly gave these two examples, I am not going to report them myself, but others are welcome to do it with more anonymity. One of them has already been removed and the other (the more popular) is still up, so I guess somebody else ticked the report buttons already.
If so it would be nice to know why one has been removed and the other not. I guess because the low poly version is harder to prove that its a derivative and therefore ok to breach licenses with?
