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.)
