It's not an agreement when your choices are "Accept" or "Wii U becomes paperweight until you accept", it's extortion. Last I checked extortion was illegal in lot of places other than just the EU.
That's how it works. If you want to continue using their services, abide by their rules. by disagreeing, you can't. Consoles aren't the only thing that does this, these types of agreements are everywhere. You can't just go to a place and go "i refuse to obey your rules" and get mad when they tell you to fuck off.
