I did a few searches and while I didn’t find that quote from Kurzgesagt’s CEO, I did find the contribution listed from a decade ago on the Gates foundation website. $570,000 paid out over four years. They also gave NPR $2,000,000 the next year.

Since I didn’t find the CEOs quote you’ve mentioned, I can only question the context around it. Would those videos not have been made because the Gates foundation specifically tied the funding to those videos being created? Or would they not have been made because Kurzgesagt didn’t have the money to do so otherwise?

Regardless, Kurzgesagt is a private company and if they wanted to conceal hidden agendas by corporate contributors, they would just keep quiet - not openly acknowledge that they made content with money given to them by some larger organisation.

If we’re going to denounce any group of people that are connected via Bacon’s Law to a disastrous corporate industry, the moral high ground will be unachievable for the entirety of our species.
