Every gaming company steals from another.

"Sony stole from Nintendo."
"Nintendo stole from Sony."
"Microsoft stole from Apple."

We get the smurfing point. Why don't you move on to something different which won't lost any points for you. The thought that company A stole from company B is old and tired and doesn't win any points for your arguments. So what if Nintendo stole that idea, and vice versa. It helps with the gaming experience, does it not? That's all that matters, not whether if it was stolen or not.
