Here’s a non-paywalled link to an article published in the Washington Post a few days ago. It’s great to see this kind of thing getting some mainstream attention. Young children have not made an informed decision about whether they want their photos posted online.
Came here to say this. If you upload pictures to instagram, they are already being processed by Facebook (“Meta”). If you have an online backup of your photos Google/Apple cloud, then they are alredy being processed.
