Neither are infringement. Artists attempting to bully platforms into not training on them doesn't change the fact that training on information would be black and white fair use if it didn't have absolutely nothing in common with copyright infringement. Learning from copyrighted material is not distributing it.
If the court doesn't just ignore the law, which has nothing that could theoretically be interpreted to support the idea that training is infringement in any way, this case will be the precedent that sets AI training free.
And you, as an individual, should want that. Breaking the ability to learn from prior art is still literally guaranteed to disenfranchise the overwhelming majority of creators in all formats, because there are massive IP holders who have the data sets to build generative AI and produce unlimited "free" content, while no individual will be able to do the same because they'll have nothing to train on. If you think Disney has a monopoly now, wait until they can train AI on 100 years of 95% of TV and movies and no one else can make AI.
