I’ve heard in a couple of places that the TV, streaming, and movie systems can’t really make an appealing offer to top-tier YouTubers. YouTubers want the prestige of being a “real” content producer, and not “just” a YouTuber, but non-YT producers can’t offer the level of control one has over their own channel. It’s not even about money, it’s about taking orders from some executive about not only content but monetization as well.
This is the way. There’s some good advice but it’s not universally applicable. The problem is, Uncle Bob defends his philosophy as if it was, diminishing the advice’s reputation.
