There is nothing wrong with Nintendo claiming their intellectual properties. If this was a form of promotion other than maybe a review of a game while showing a bunch of gameplay it would be different. But it isn't. These people are taking a product and infringing on the IP's, same goes for Sony, MS, Ubisoft, EA, Activision ect. In an attempt to allow these people to continue to do what they are doing it is quite natural for what is happening to happen.
Normally when an IP is featured or shown it is by consent, with youtube that has almost completely went out the window till the last few years. Especially since gaming and movies are a viewing medium, it is well within their right to do this. They do see that there might be some positives in it which is why they are allowing it to happen.
Gotta figure out how to set these up lol.
