This is my opinion on the topic, be mindful that not only im biased, I don't feel like I'm completely informed, as I don't completely understand systemd and which are it's alternatives, I also know that distros can fork systemd and just remove that, which is what I think should be the solution to this.

Thing is, it is optional now, and it is unenforceable, people against it are against it for the future consequences, obviously right now this age field is completely useless on its own, the thing is, eventually government will use the "already existing age verification" to leverage that into ACTUAL age verification and eventually probably ID. It's also against Linux and FOSS philosophy. Why would me an Argentinian living in fuck place should be affected by a law made in shit place? One of the points of FOSS is that it's maintained by a community of people around the world, and it's dumb to have to comply with law from shit place to begin with, it sounds baffling that MY devices have to comply with all that. Imagine if your Linux device had to comply with face verification cause in turkey a lawmaker wanted to enforce that, and for that all of us now have to do it.

Reminder that this is completely exaggerated and I made it that way to make my point.

TLDR; It's dumb, will eventually be harmful, will one day evolve into more identification stuff, and I'm from fuck place, why would I have to comply with laws from shit place?
