OpenAI and Microsoft are under fire in a class-action lawsuit over alleged web scraping to gather private data for training AI models like ChatGPT. The lawsuit, filed on Sept. 5 in San Francisco, accuses the companies of using stolen private info, including personal data from countless internet users, without consent. The plaintiffs argue that without this data theft, products like ChatGPT and DALL-E wouldn't be the billion-dollar businesses they are today. They seek damages and a halt to the alleged illegal data scraping.
