evidence: How will this play out? Meta says that "from next week" all adults in the UK who use Facebook and Instagram "will start receiving in-app notifications to explain what we’re doing". These notifications will apparently include information on how you can "access an objection form" so you can opt out of your data "being used to train our generative AI models". [...] Meta has also added that "we do not use people’s private messages with friends and family to train for AI at Meta, and we do not use information from accounts of people in the UK under the age of 18". However, that doesn't mean that photos of children uploaded on other public accounts – for example, by family or parents –can't be used for AI training, so it's best to get those privacy settings locked down. While this all may seem invasive, at least those of us in the UK and EU have the option of opting out of Meta's AI training – we recently saw that Facebook and Instagram users in Australia have no opt-out option, despite Meta admitting to scraping posts and photos in the country from as far back as 2007.
