Correct. But at least we all can agree that the OG pillars of sciTube (and adjacent content) who keep it fresh with their unique forever updating style are the less guilty of those tactics: 3blue1brown, Vsauce, CGP Grey, Steve Mould, Matt Parker, Numberphile & 3 or 4 more that escape the tip of my tongue. They all do this for a living, but only one created a loot box and all profits go to research.
