I think the idea is great but the split that Nintendo demands is too big. When I bothered with Youtube videos and my channel I had some Pokemon videos that I could have monetised. When I intended to start it there was a disclaimer where with several other things was written that I couldn't monetise my videos when if it has recording of a video game. With the NCP smaller channels, who are not in a MCN, seem to get a guaranty that they can monetise the video without any hassle.
As for bigger Youtubers. While I think that being an entertainer on Youtube is a legimitate job they must be aware that they seem to be in a legal grey area and are depended on the good will of the publishers.
But they are also pretty detached. I read boogie's tweets yesterday and he talked about that if Nintendo gave up on NCP the bigger Youtube channels would
fix the Wii U's situation. Given that the much of the Youtube scene didn't give a crap about Nintendo and the Wii U even before NCP I doubt they are just waiting to release videos about Nintendo games.
And there seems to be demand in the viewership of boogie, Angry Joe, etc. for videos about Nintendo. And they themself often say that the Wii U has the best line up. But they are refusing to give these games coverage because it makes them less money. I know that they depend on the money for a living but i think what they do is an asshole move.
For me there is no good or bad side in this. Only greed on both sides.
P.S.: Did Angry Joe even tried to do an review for an Nintendo game? Because as far as I know he only uploaded a Let's Play of Mario Party (and Mario Kart I think?).
