So I was writing an arch involving a blue dragon with my players and I watched this video by a youtuber, AJ Pickett.

Then I wanted to know more about them so I found this wiki and this amazing report on blue dragons,
https://dragons.fandom.com/wiki/Blue_Dragon_(Dungeons_%26_Dragons)
At the very beginning and at the 3min mark he begins to say almost word for word, what's written on this fandom page. At the beginning of the video he mentions that he pulls on 3 editions for his information and doesn't mention this page.
Maybe he copied this page? Maybe this page copied him? Maybe it's all his work? I checked the revision from 2010 (10 years before the video was released) and it still has the same script for the most part.
I'm sure this page also pulled from source material in earlier editions, but I don't have access to them to verify if it was copied word for word. It could definitely be that both the youtuber and the page are pulling from the exact phrasing from the source material and it's just a coincidence.
If someone has access to earlier books or know who wrote this, can you please verify for me that the page is using exact cut outs of paragraphs from older editions?
