maybe this is the real reason why governments don't switch to Linux: the nerdy images. Because we can't have that in an official government building, no sir, it's all numbers and abstract icons in here please :-)
I also don't foresee governments regularly using Krita.
Politics is almost entirely about image over substance. If you're a government bureaucrat, do you really want to risk your/your party's electoral chances by proposing switching from Big Tech to something with anime furries all over it?
