Wat.
You actually think they're afraid of Angry Joe not liking their games, and that is why they're doing this? Are you for real?
Nintendo wants trustworthy companies and people that can do good coverage of their games. They don't have to always be positive about Nintendo-games to be part of that group. Angry Joe is simply not a personality they want to be partners with. Can Angry Joe still make Nintendo-videos? Yes. Can Angry Joe still do reviews of Nintendo-games? Yes (in fact, he can even make money off of them). In fact, all of us can do our own review videos if we like!
And "anti-consumer"? What are you even talking about? You're not a consumer anymore, once you start making money off of it.
Though, I'm not surprised not everyone gets this. Not even Angry Joe seems to understand it:
(By the way, him "buying" a Wii U is a lie, seeing as it was donated to him").
