It's weird, but I can actually believe that this guy just didn't realize until he was told, like he said in the video. Like, I feel like I'm usually decent at sussing out people who seem excessively positive to a suspicious degree, and while he might have been, he didn't come off as entirely fake, if you get me. Like horrifically irresponsible, but not necessarily lying.
But maybe I'm off the mark. I've known of this guy since before he started the charity, but I've only watched one of his videos iirc.
