I don't really keep up with these Tech/Soft tubers, but watch a video on occasion. Can't really say I find something-imagen guilty of this, but like I said I watch the occasional video, not the stream. What I've watched from him is generally about what he agrees/disagrees with and he also tells you why he thinks that. Often reading articles/blogposts. Not to dismiss your opinion, but I would put him in the entertaining with substantive arguments category.

IMO software education/tainment suffers much worse though. They teach you how to do X in only this specific way with these specific tools, generally sponsored. Not the admittedly far more boring basics to do it yourself, or how to actually use these tools in a broader sense.
