@Some_Guy_Here While you are wording things wrong, you are correct that the original mod was stealing IP from Ferrari. It's probably the wrong word, creating a copy of the real car and distributing it is illegal without the correct licencing.
Modding exists in a legal grey area, where manufactures turn a blind eye to the activities of modders for a variety of reasons, mostly because it isn't worth the expense of chasing them. But they have acted before to protect there rights, most notably Porsche with the Carrera Cup mod for rFactor 2.
However, this doesn't change that the ownership of the model belongs to
@SalamanderSoldier, and it appears that Codemasters used it without proper licencing. The model being available on Turbosquid does muddy the issue, and most likely will mean that all he'll get is the model purchased from there.
