Dark mode has a strong preference among some computer users because it works better in dark "computing caves" with low ambient light; when you consider that older screens were relatively dimmer and had severe glare issues, the computer cave was itself a sensible way to do computing. I know I was all about dark mode 15 years ago or so with my first LCD monitor. But it's also primarily a young person's thing to be able to stay in the cave. Older people are more often put in a position where strong ambient light is assumed, either because of job/household environment or because their eyesight starts to prefer it.
