Eight US states have filed lawsuits against OpenAI, citing data privacy issues related to ChatGPT. The lawsuits allege that ChatGPT has access to user data, including sensitive data, and claim the AI system is misleading users. Additionally, there are reports of a significant drop in ChatGPT traffic, which has been attributed to tracking issues. OpenAI has also integrated ChatGPT's functionality into Chrome tabs, allowing the AI to track and review user browsing behavior.
