However, what’s gonna happen should the attempts to age-gate the XDG portal screw over alt-init distros like Artix too? My guess is maybe they start blocking regions which force age gating like Arch Linux 32 is doing.
The first step always seems innocuous don’t worry they will do in baby steps so people like you don’t notice it before it’s too late.
