Answer: Because light attracts bugs.

Easier on the eyes...

Prolongs the life of your LED screen, particularly if it's OLED.

I've never understood why so many people unironically say dark themes are easy to look at. Maybe it's because of my astigmatism, but I find the vast majority of dark themes unbearable.

@phi1997 @ferricoxide @nixCraft If you wait N years, you'll see why some people prefer dark mode - where N is large enough that you'll start having cataract issues. BTW, some of the software I've written picks dark mode or light mode based on system settings, so it will hopefully do whatever the user wants automatically.

O365 annoys the piss out of me: defaults to bright mode, and when you go to change it, it offers dark mode or to match your system setting. Like, "why wouldnt it just default to the system setting??"
