The video series he does is to essentially put the viewer in the shoes of the diagnosis process and mystery of it all. Is it irresponsible when videos showing mystery stories dont lead with who the killer was or when jokes dont start with the punch line?
If you just clicked the video you’d see the first image is a disclosure mentioning that this kind of case is uncommon and explaining the circumstances in which you should seek medical attention.
Overall I dont see why putting all the facts in a headline makes it more or less responsible. You want to know the story then watch it. It’s not like the story is misleading or wrong, and his video in particular is pretty thorough in going over exactly whats happening and why.
