When I started on YouTube, I made the decision to never make content based on anyone else's work. So no reviews or reactions or tags or anything like that. I try really hard to stay in that lane, so I tend to avoid channels that are exclusively about other channels, because I'm very prone to being sucked into drama as a viewer, and it's a complete waste of my YouTube time. So I know who they are, but I try never to watch or listen to anything that is talking about third parties on YouTube as a main source of content. It's just a personal preference, but I think eventually, the snake eats itself, if you go down that road.
