Ideally if we were to add it to the bitcoin.org home page, it would be nice to keep it neutral and edit the last part of the video to mention bitcoin.org instead of the author's site.
This video is the product of their work. I won't blame them for taking credit for it and putting their own website link at the end.
So I don't think it is necessary to edit the video. However, a small textual note could be added above the video, saying that this video was not done by members of the bitcoin.org community.
It is done by members of the bitcoin community.
