Hmm? This is Medium doing a reasonable thing. They comply with Do Not Track, but people can embed videos on sites that do not comply. Here they do a reasonable thing, and show a message to people with "Do Not Track" enabled, letting them know that they can still click through and see the video, but the site they are directing you towards might track you. Medium is just a blog hosting platform, as far as I know they don't control the content that gets posted. What would you prefer they do; not allow embedding YouTube videos? Not warn you that the linked content tracks you?
