I'm not convinced about this. In the article, they also say that they could feed the model with copyright law like that would fix the issue. Unfortunately, not only the LLMs have already been trained on law taxtbooks and codes, but we also have examples of people on the internet were models disregard precise instructions only to apologize later.

Note that this is not to be seen as an excuse for OpenAI to avoid responsibility, just like parents are responsible for damages caused by their kids.
