Right, but that just makes it a failed defense, not a scheme to dupe artists into false confidence. Maybe the result will be similar but I don't think the intent here is a con, it sounds pretty genuine.
I think of it as a claim like "we almost have a machine that violates thermodynamics". To avoid confusing the layman that will automatically assume an unlimited energy has been created said claims must be well defined as to what has actually been accomplished.
While the artist in question can have the best intentions, conmen will swoop down on this and productize it, and then artists will be sad and confused when it has zero long term effect on machine learning. That is, except making machine learning more resilient to adversarial attacks.
