Tons of those are (as the site admins admit) models that are themselves infringing on copyright, and thus any license based on copyright ownership is invalid.
You can't enforce a license on a 3d model you in turn stole from a game.
Just to make sure I understand you right: the argument is that
Acteur a has a no permissive copyright
Acteur b has a non-commercial copyright on a model that infringes on a's non permissive copyright
Acteur c now can freely use it commercially, because b's copyright notice is invalid as it was never in a position to grant a permissive license
The stuff you learn on HN is truly breathtaking.
Thanks for clearing that up, that opens up a lot of avenues for future developments
