Don’t get me wrong, I’m all for privacy. But between setting up the birthdate when creating my children’s local account on their computers, and having to send a copy of their ID to every platform under the sun, I’d easily chose the former.
I’d even agree to a simple protocol (HTTP X-Over-18 / X-Over-21 headers?) to that.
Also this goalpost will move almost immediately. What if the parent doesn’t understand why the OS is asking for a DOB and they type whatever? What if the parent doesn’t log out and the kids use the adult account? What if the kid is really smart and bypasses the check (I think this could actually get bypassed easily)?
Rather than rolling back this rule they’ll just go even further and say the OS must analyze every action and utilize every input (e.g. microphone, camera) to determine the age of the current user and that controls need to be at the hardware level and OSes need to get state certified, etc. Before long only Windows, Apple, Google, and maybe RedHat can comply. An entire community of Linux enthusiasts destroyed. And as some bills have stated, rather vaguely, this can apply to something as simple as a calculator!
Which we have already seen with content ratings. Instead of using the rating to inform themselves on what content to allow their child, they basically relied on the retailers/theatres not selling access to people below the age.
