Because of this, it isn't at all clear that this model can be copywritten in the first place: it isn't itself an expression, but is merely the output of an algorithm that was itself released as open source. Maybe you could argue that the model is under the same license, under an argument that it isn't similar to how a compiled binary is considered a derived work of the source code... but that license is GPL, guaranteeing the right to distribute such binaries. Alternatively, maybe you could argue that the code is more like a compiler and the model is a derived work of the training data set. But, not only did Facebook not make or own the training set, they specifically used an open data set (that was the point of the research in a sense) that any of us also have similar access to. > They have the right to do this. So, not necessarily; and, as far as I am concerned: not at all likely.
