Christ that guy comes across as an arrogant prick. Here, "Veritasium", let me rephrase your shitty, overly long, condescending video: "I deceive my viewers because it makes me more money".
I'm not going to rewatch it, because, as you said, it's long, but what he's saying is that there's a difference between baiting and never delivering and bating and delivering.
Also, educating isn't just about putting forth the facts, but also persuasion and spreading. It does coincide with him making more money, but there's nothing bad about that.
