evidence: If you’re uncomfortable with having Meta use your personal information and intellectual property to train its AI models in perpetuity, consider opting out. Although Meta does not guarantee it will allow this, it does say it will "review objection requests in accordance with relevant data protection laws." [...] Users in the US or other countries without national data privacy laws don’t have any foolproof ways to prevent Meta from using their data to train AI, which has likely already been used for such purposes. Meta does not have an opt-out feature for people living in these places. A spokesperson for Meta says it does not use the content of people’s private messages to each other to train AI. However, public social media posts are seen as fair game and can be hoovered up into AI training data sets by anyone. Users who don’t want that can set their account settings to private to minimize the risk.
