@Chandlero So you would assume that a greater portion of viewers watches the video solely because of the game, not because of the streamer?
How can you tell how many people maybe watched the video, just because they are subscribed to the streamer?

@JamesR To stay with your example: isn‘t it exactly as if the company, on which instruments I play music and sell it, wants to get a share of said music‘s revenues?

@Chandlero Because Nintendo demands a bigger cut of the (ad) revenue, yet the whole work is done by the Streamer/Youtuber. Nintendo's work is done as soon as they have finished the game - that's what you pay for in stores.
They aren't involved, not even in the slightest, in the creation process during the stream/video.
