If you could separate the information from the intellectual property, sure; but if the model is also capable of generating a similar article, that's the point where it starts infringing on the IP of all the authors whose articles were fed into the model.

So in practice, no, it shouldn't. Not because that information itself is bad, but because it probably isn't limited to just that answer.

In summary, I think it is definitely a problem when:

1. The model is trained on a certain type of intellectual property 2. The model is then asked to produce content of the same type 3. The authors of the training data did not consent

And slightly less so, but still questionable when instead:

2. The IP becomes an integral part of the new product

which, arguably, is the case for any and all AI training data; individually you could take any of them out and not much would happen, but remove them all and the entire product is gone.
