Anyone can make a mistake, mistakes can be a good way to learn provided the damage is not too severe. It is not making a mistake or two that is the issue, it is the egregious way he puts making money at a higher value than correcting that mistake while other pay the cost. He has a drive to publish content even when he knows it has errors in it. He literally published a video that not only gave a review on a product fitted to the wrong part, but then went on to screw that company further by selling the prototype for click bait.
GN is not about entertainment; it is about getting good information on tech. Be a comedian as much as you like, but if your bread and butter is about giving a review, then at least make that review plausible. It is not a big ask.
