Plus it’s always a video, but never actually uses the medium. It’s just shots of the host talking to the camera. Very very rarely showing clips or screenshots that could even better be embedded in an article.

Can you do a lot with a video, if done well and for the right subject? Of course, and for those it’d absolutely be the correct choice. But people like the guy linked in the OP are neither capable of nor interested in doing that, as it’s just a business to them. It increases income, so long youtube videos it is. That’s one big takeaway anyways: Content creators talk about this shit not because they care, but because it gives them money. It’s a business, not a passion.
