the vision of an age verification scheme like california's is that an adult can set up a child's account to be in a specific age group, then have the system automatically inhibit the child's access to applications that they aren't allowed to access. this could be further built upon by laws requiring ex. gambling services to check this signal before allowing the user to sign up. of course this can be circumvented, but all laws can
the way this will effect linux is not going to be described well by media because they don't tend to have the best understanding of the open source ecosystem. it will be up to distributions (not linux itself) to ensure there is an age step in account setup and a library for accessing that information. this is fairly simple to implement and work has already started on it
additionally, i am not interested in debating anyone on whether age verification should exist. im trying to clear up misinformation about a very simple bill that anyone can read. if i don't know you, i have no reason to discuss philosophy with you
