That's a "prefers-color-scheme: dark" style: if your machine is set to light mode then it's black on white, well okay, very dark gray on very light gray. (Also the text in dark mode is slightly gray but it's very slight).

I don't think it's totally crazy to present text like this to users who are advertising a preference for white-on-black (though of course there's an argument to be made about the difference between "dark" as a UI choice and a content choice... really this feels like something your browser should let you opt out of despite your OS colorscheme choice).

Preferring dark mode does not necessitate presenting #f0f0f0 text on #000 background. Lots of websites out there that present a proper dark mode when they sniff the preference.
