evidence: It isn’t new for tech companies to use your data to train AI products. Netflix uses what you watch and rate to generate recommendations. Meta uses what you like, comment on and even spend time looking to train its AI how to order your news feed and show you ads. [...] Meta told me it didn’t train its biggest generative AI model, called Llama 2, on user data — public or private. However, for the AI chatbots and image generator features the company unveiled in late September, Meta did use "publicly shared posts from Instagram and Facebook — including photos and text." The company said it didn’t train them on private posts or private messages with friends, which is good. But shouldn’t it ask permission to use data from "public" posts that surely includes many photos and details about people’s families and private lives? To avoid that, you’d have to have set your account to private, or quit Instagram. Like Google, Meta also claims the right to use whatever you share when you’re using its new generative AI products – like your conversations with its chatbot – to train its AI.
