I feel like most people are just gonna read the title and get the wrong idea about what is written in the page. So I will quote this:
And this is why I am of two minds about this issue. On the one hand, I fully understand that the various developers involved with these efforts want to make sure they follow the law and avoid getting fined – or worse – especially since compliance requires so little at this time. On top of that, these changes make it possible to implement a fairly robust set of parental controls in a centralised way, keeping the data involved where it makes sense, so it also brings a number of benefits for users. There really isn’t anything to worry about when looking at these changes in isolation.
On the other hand, though, I also understand the fears and worries from people who see these changes as the first capitulation to age verification, nicely making the bed for much stricter age verification laws I’m sure certain parts of the political compass are already dreaming about. With so many Linux distributions, BSD variants, and even alternative operating systems having their legal domiciles in the United States, it’s not unreasonable to assume they’re going to fold under any possible legal pressure that comes with such laws.
I’m not rushing to replace my Fedora KDE installations with something else at this point, but I’m definitely going to explore my options on at least one of my machines and go from there, so I at least won’t be caught with my pants down in the future. The world isn’t ending, age verification hasn’t come to Linux, but we’d all do well to remain skeptical and prepare for when it does make its way into our open source operating systems.
It is not that, "there is nothing to worry about age field creeping into sytemd". It is that in the current ecosystem in which most large open-source projects live, it is easier said than done to take a principled action against early compliance with such laws. Which is much more reasonable than trying to undersell this change as "eh it is just an optional age field". It is not, it is a statement that when asked to comply with surveillance laws, they will be met with minimal resistance.
