Here’s a concise summary of the news article:

Facing lawsuits over Meta’s use of copyrighted books in its AI training, a coalition of publishers, law professors, and copyright advocacy groups have filed amicus briefs arguing that the practice doesn’t constitute fair use. These groups are challenging Meta’s reliance on “pirated books,” arguing that unlike the Google Books case, Meta’s use exploits the creative content of the books and could set a dangerous precedent, leading to a “cascading effect” of copyright violations. The legal challenge focuses on the distinction between simply accessing information and leveraging the expressive elements of copyrighted works for AI training.
