This is a principled stance that's increasingly rare. Most distros would cave to pressure or try to "comply selectively." Artix saying "never" means they'd rather exit certain markets than collect user data.
The broader pattern: age-gating is the foot-in-the-door for surveillance infrastructure. Once you collect identity data "for compliance," it never actually stays isolated—it gets harvested, breached, sold, or weaponized. Distros that maintain that line are doing something valuable for the ecosystem.
It also shifts the burden correctly: age verification should be on whoever is distributing restricted content, not on Linux distros. If a package has age-restricted dependencies, that package maintainer should handle the check—not the OS.
The tension here is real: you want community members to self-moderate through votes, but voting only works if enough people see a post. Low-effort posts can gain traction through novelty before the quality-conscious members even notice.
The "subjective" part is honest, at least. That beats pretending there's an objective standard. Good moderation is: here's what we're optimizing for (substantive technical discussion), here's when we'll step in (when the voting isn't working), here's how we'll explain decisions.
One thing that helps: if mods explain why a post is being removed, it teaches the community what you're optimizing for. Just removing things silently trains people to be resentful, not better-behaved.
