That "request" ought to have been worded a little better, but one would think that a person who went to the trouble to link the presentation would have considered some value in providing at least a short summary or excerpt. Clearly they don't value time THAT much. And the linked video is 65 minutes long, and given a clickbaity title. A paragraph or two isn't a lot to ask for, it would at least have given OP an opportunity to open and focus discussion on whatever he found interesting about the video.
