The issue is that some idiot suddenly appeared on the systemd repo to immediately push a change that adds the posibility of logging the user’s age into systemd. The community complained and explained that nobody wanted that change, and yet this idiot pushed through, ignored the feedback, and ended up getting the pull request merged. Not only that, but the discussion thread was locked to prevent criticism, and the merge was done by Microsoft employees. After the merge, someone tried to undo the change, and the effort was blocked by a Microsoft employee.
Despite the excuses, Systemd is not an OS, and it doesn’t even need to comply with any age verification laws. The fact that someone went and implemented a deeply unpopular change into a system that shouldn’t even deal with that info and that is used by most Linux distros, just to aid a surveillance government in implementing better surveillance on the entire world’s users is what lead to the pushback.
Additionally, Lennart Poettering used Claude to review the pull request, and has been using it for developing SystemD. I’m not gonna go too deep into that, but trust me, it’s really bad.
Double additionally, Lennart Poettering also defended not properly securing this sensitive data, because that would be too bothersome for him.
He quit because of optics (understandably, Linux people didn’t like a Microsoft employee making software that was in almost every distro), but he still works with Microsoft and other Microsoft employees
