The use of pirated text in datasets like Books3 raises significant concerns regarding intellectual property rights. By scraping and utilizing content from shadow libraries without proper authorization, individuals like Shawn Presser are potentially infringing on the copyrights held by authors and publishers. This unauthorized reproduction and distribution of copyrighted material not only undermines the creators' ability to control their work but also deprives them of potential financial benefits that would have come from legal access to their texts. It sets a dangerous precedent for AI development, where the boundaries between fair use and infringement become blurred, leading to ethical dilemmas surrounding data sourcing practices.
