The concept of debunking doesn't apply here, outside of the right-wing media bubble. The author estimated that 75% of the information was likely accurate. Is that what you think was debunked?
Why don't you ask Erik Wemple of the Washington Post? He's had a lot to say about the bogusness of the so-called dossier, and the media (including his own newspaper) that publicized it far and wide. <https://www.washingtonpost.com/opinions/media-steele-dossier...>
Do you know which organization you're referring to? I suggest you read the reporting from the major outlets at the time, it's purely factual information about the dossier.
