Some people have alluded to this, but I find it sad that so much energy in our modern society goes towards trying to exploit arbitrary particularities of arbitrary platforms. Even if we set aside the stuff like "you're taking a risk building on YouTube because they could ban you", there's the more practical stuff about how the plan is all about the title and thumbnail. Like if YouTube somehow switched to letting you have two thumbnails, or some other UI element that you could customize, suddenly everyone playing this game would have to scramble to figure out how to maximize in that environment.
It just seems to me like following a rich person around hoping some coins will fall out of their pocket. It's a parasitic ecosystem that encourages content to focus more and more on "what works" in the self-perpetuating context of that ecosystem, and less and less on making contact with any kind of external reality.
