Very strange indeed. I wonder if Kurzgesagt has done something to upset the crowds? I haven't watched any of their stuff in a year or two, but the ones I did watch were excellent and I thought they were well liked and popular. And accurate. And willing to correct their mistakes.

Maybe I've missed something.

Every Kurzgesagt video I've ever posted has gotten this reaction. Some people seem to feel that they have sold out, and yes adamantly hate the click-baity titles.

It's a common issue on the internet where people refuse to deal with nuance and subtlety, preferring instead to simply "like" or "dislike" - I would even go so far as to guess, with many such votes having been offered without first having watched the video.

It is still an option to simply continue scrolling down without voting on something... but no, they feel like their opinions must be heard, regardless of how unqualified (not having watched it) or unthinkingly offered. In short, this place is still social media, after all.

Edit: here is a relevant previous discussion that seems of interest to you. It was this discussion that convinced me to stop sharing Kurzgesagt videos - not because they are bad, but bc people on social media tend to not enjoy them. Possibly heavy curation of the presentation of them may work - at a minimum making a new title, though I would still think that the first 30-second lead-in to the video would remain off-putting to people who upon seeing that aren't really willing to give it a further chance.

And what do they have to lose?

Quality of life, it's more complicated than just live or die, regardless of whether you think the patients should be able to choose for themselves or not.
