Because during an emergency, someone shouldn't have to watch an ad when accessing life saving information. That would drive anyone mad.
>And what other platforms "should" do this? Do phone OSs have to have CPR videos embedded for quick access?
Not quite sure where you're going with this speculation, but I wouldn't exactly call a medical emergency an "edge case", maybe that's just me.
You don't ask book stores to provide quick access to medical books in case of an emergency.
College lectures, cooking videos, work out instructions, car repair instructions, guitar covers, I could go all day.
It is a video sharing platform, and the most popular one at that. Entertainment might be the most popular use case of the site, but it's still a tool for accessing information.

Of course not, the person would be dead before you got there lol.
My whole argument is that YouTube is very often used as a tool for quickly accessing information, so it would be really beneficial to provide something that could save lives, what is the problem with that? From a business perspective, it might even be a good PR stunt.
