My observation above was just from personal experience. But after making it I searched 'Kurzgesagt' on YouTube (just wanted to see what videos they'd recently produced) and, as well as their recent videos, that search also turned up one called Kurzgesagt: billionaire propaganda, trusting science, and effective altruism [1] which I've now watched and found that my observation has been made by others and analysed in quite some detail. That video mentioned some others on the same subject [2-3], which I haven't watched but also look interesting.
