So, I can see where commercial OSes, like Windows and MacOS, but maybe including Chrome, Red Hat, and similar, would welcome the requirement to collect user ages. Another piece of user data for telemetry, ad serving, etc, with the cover of ‘government made me do it.’
Linux is always going to have weirdos, ready to spin up their own distribution for their own reasons. Like, I remember when the majors all started switching from init to systemd. There’s still a bunch of distros, even some good–sized ones, that avoid systemd. If age verification works its way from facilitating tools to distro mandates, I guarantee that there will be distributions created in jurisdictions without age mandates that exclude any tools that require age validation or with systems to spoof age validation. It’s simply too easy to change linux to avoid this.
If the birthdate field is just a random number, then I don’t see why anyone cares - it would have less personally identifying information than the MAC address. I thought the whole reason people are up in arms about this is the proposal/hypothetical where the OS is required to validate that field against government ID databases, thus giving a third party - the OS vendor or whatever contractor performs the validation - a link to real world identity of any computer user.
