The moon wasn't the predominant source of light at night for most pre-industrial people. Fire was, and is what we evolved with, which is likely why red light doesn't cause your eyes to constrict (https://thehikingauthority.com/red-light-night-vision-a-myth...)
I would hesitate to believe that crowds sitting around a bright fire at night will produce more viable offspring than those fumbling in the dark away from the light.
The evolutionary mechanism for selecting blue-sensitive rod cells in our retinas along with red-sensitive cone cells must surely be unrelated to the sodium emission spectrum, given that so may other mammals have similar retinas but lack fire-making skills.
I don't know enough about the relevant physiology to judge the article as a whole, but this bit is not correct:
"That’s why military grade night vision goggles always use a green light. You get a much clearer sight picture with extra contrast while preserving most of the night vision once the light gets shut off."
The trend these days is towards white phosphor in NVDs. This is because, while green is indeed better if you have to look at it and away repeatedly in low light, white is significantly better at producing high-contrast images. And you do want high contrast to be able to spot things when it's dark.
