I think that Youtube thing's more likely, they HAVE approached Notch about monetizing Minecraft footage and honestly Nintendo doesn't seem like the kind of company that'd aggressively want to monetize Youtube videos, so it's probably more someone at Youtube thought it was a good idea for whatever reason (they could've had issues with other companies that felt they deserved it and there IS a logic to it: it's footage of their games afterall) and decided to start aggressively approaching companies about this. Not realizing how much it fucks up something we took for granted with magazines and even TV shows in the past.
