A US bill, the Parents Decide Act, proposes to require operating system vendors to verify the age of users setting up a new device, which would create a national identity layer and potentially erode anonymity and free speech. The bill aims to protect children from online harm, but critics argue it is disproportionate and could lead to mass surveillance. The legislation would obligate providers to collect birth dates and develop a system for app developers to access age information. This would effectively create a content control system, with Apple and Google as gatekeepers.
