Kurzgesagt tends to push a lot of pseudoscience (e.g. carbon capture tech) and other stuff following the investment interests of their founders.
I like their animation style and honestly I wish they used proper data sources, however if you check the sources they mention on some of their more dubious videos they all come from some made up source.
This is particularly upsetting with everything related to parroting whatever Bill Gates is pushing (artificial meat, carbon capture, inequality is the teacher's fault, climate change isn't that bad, etc.)
Ys. It didn't feel very convincing, nor did they actually address the issue of them citing a company Bill Gates owns in order to support another one he owns.
Seeing where the money is is a good way to see why someone says what they do. That's disappointing. I'm mostly there for their space videos personally and so far there doesn't seem to be any propaganda there.
