See the result in this page: dark mode users were presented something broken that completely ruined the main effect of the article, where it wasn’t immediately obvious why it was broken, and which they can’t easily switch away from; whereas if it had done nothing they would have received something admittedly inferior in an important way (light) but functional, by default, and if they use Dark Reader, something superior and functional.
