> I have found his reaction videos tedious with the excessive commentary

I don't follow any of the mentioned youtubers, but their stuff occasionally appears in my recommendations. I don't understand the point of videos where someone just scrolls through a blog post and reads it out loud. It comes across as narcissistic and an attempt to piggyback on anything to "create content". There's rarely any added value, and it also feels extremely inefficient to watch such "reaction videos" when I could just skim through the text myself. I guess I'm too old and not part of the target audience.
