Wow, your deductive reasoning is mindblowing. Thanks for explaining it to us in elementary logic so we can follow.
Whatever you wanna call the control stick, they confirmed all control styles a long time ago. It's just like Mortal Kombat has, you just have a choice, which works for everybody.
As far as shelling out more money for a classic controller or a GC controller... everybody should own both anyway! They're cheap! It's not making a $50 game $70. The controllers work on MANY MANY MANY other games. Some people just wanna make Nintendo look like a bunch of cheap bastards.
