The point is to create a scenario where there is obvious overwhelming support for something from the consumers that cannot be ignored. If there are many calls coming in all about the same thing, that *will* get to people who have power, especially if it is large numbers they don't usually see.And customer service will say "uh huh, thanks for the comment" and do nothing, because they don't have any way to make suggestions for upper management. They are there answer questions and deal with customer problems. And as I said, Project Rainfall was "an avalanche of dissatisfied calls", and that caused Nintendo to delay release of the games.
I can't believe there are actually people arguing against voicing your opinion. When did that become a controversial idea, to politely state you don't like something? This is blowing my mind right now. That is a ridiculous level of treating a business like they are a friend or something when you try to put the brakes on polite criticism.
