I agree with this. Default, unconfigurable light mode has been around for a while, and infrastructure like the Dark Reader plugin is around to address this. There is no such thing for light mode, though.
In my opinion, light mode is better than dark mode in most situations. The only situation dark mode is better than light mode is when you're sitting in a dark room with your screen as your only light source, and most of the time that's not really a healthy situation to be in. Dark mode is a crutch. Turn on a light or go to sleep.
Light mode might be annoying to read in no-light environments, but dark mode is nigh impossible to read in high-light environments. Ever try to read a dark mode UI on your phone on a bright summer's day? Can't read a thing, even with brightness cranked all the way up.
