It’s a bit hard not to be cynical when he himself describes how he developed his channel by optimising and a/b testing everything “like a psychopath” including the amount of views per dollar given away - he says himself that 100k seems to be the inflection point, you don’t get so many more views by going from 100k to 500k or 1m. Not once did he ever appear to have thought about the impact on the lives of the people receiving this random lump sum, which plenty of research on lottery winners shows is often very disruptive and negative on their overall long term wellbeing. As for his “donating” for blindness surgery etc, there are plenty of actual charities staffed by volunteers working hard day after day, he could easily donate quietly to any of those and he chooses not to.
