I generally prefer written articles as well, but this is for camera reviews. The video format, when executed well, is actually a great fit for this. I learn more from watching a YouTuber handle a camera and operate it than I would from someone describing it in text. Video conveys an extra dimension that is lost in text for camera reviews.

The YouTuber he’s attacking (for unknown reasons) also does microphone reviews and other things related to video production. Video really is a good format for these.
