Disney, Warner Bros. Discovery, and Universal have filed a joint lawsuit against the Chinese generative AI app Hailuo, accusing it of extensive copyright infringement involving their protected works, including characters from major franchises. The lawsuit alleges that Hailuo's business model is built around infringing on these copyrights and actively encourages users to create content using the studios' intellectual property. This case adds to a growing trend of legal battles between media companies and AI developers over copyright issues.
