Ziff Davis, owner of media brands CNET and IGN, has filed a lawsuit against OpenAI, accusing it of copyright infringement. The company claims OpenAI "intentionally and relentlessly" replicated millions of its articles without permission and stripped copyright information from content used to train AI models. Despite Ziff Davis’ exclusion requests via the robots.txt file, OpenAI allegedly ignored them. Ziff Davis demands OpenAI cease using this content, asserting the need to protect its intellectual property rights.
