I honestly dislike YouTube content for many of the reasons stated in this thread. YouTube's content creator model is designed around attention. The more attention something gets, the more the influencer is paid. As such all content needs to be tailored about retaining attention vs straight out providing education and value.
I've found value in any part of the audio system is a personal thing. I enjoy providing value to those who seek it, rather than to broadcast something in a shiny way and try to influence people on it. I do review products I deal for periodically, but only when it truly knocks my socks off. When I do review products, I make this content in the format of exhaustive written reviews rather than through videos. I don't get paid for my reviews, nor do I get money for the amount of traffic or views it drives. I just want to express my experiences with the gear and hope it helps someone out. But hey, I've only written two reviews, and in most cases, I prefer to just add value by providing guidance in these forums.
