Consuming content illegally is by definition a crime, yes. It also has no effect on your output. A summary or review of that content will not be infringing, it will still be fair use.
That their use is infringing and a crime is your opinion.
“My opinion”? have you read the headline? Its not my opinion that matters, its that of the prosecution in this lawsuit. And this lawsuit indeed alleges that copyright infringement has occurred; it’ll be up to the courts to see if the claim holds water.
I’m definitely not sure that GPT4 or other AI models are copyright infringing or otherwise illegal. But, I think that there’s enough that seems questionable that a lawsuit is valid to do some fact-finding, and honestly, I feel like the law is a few years behind on AI anyway.
But it seem plausible that the AI could be found to be ‘illegally distributing works’, or otherwise have broken IP laws at some point during their training or operation. A lot depends on what kind of agreements were signed over the contents of the training packages, something I frankly know nothing about, and would like to see come to light.
