An init system does not need to know my personal details; it’s for starting programs in a specific order just fuck off with this shit. You don’t even have to capitulate to this stuff and these freaks are out here doing it preemptively like they expect a fucking pat on the head for being first in line to dive tongue first on to that boot.

Systemd isn’t an init system. Systemd-init is an init system and it is a part of the systemd suite.

Whatever the fuck it is it doesn’t need to know how old I am to do its job.

It doesn’t need to know your age. It just provides a way to take a note of your birth date, only if you want to. The system already has a place to write your name and home address. All are optional and practically nobody uses them.
