Why is this? Why do we deliberately build things that confuse the people who use them? Answer: Because the people want the features. Because simplicity is a myth whose time has past, if it ever existed.
Make it simple and people won’t buy. Given a choice, they will take the item that does more. Features win over simplicity, even when people realize that it is accompanied by more complexity. You do it too, I bet. Haven’t you ever compared two products side by side, comparing the features of each, preferring the one that did more? Why shame on you, you are behaving, well, behaving like a normal person. The complicated, expensive toaster? I bet it sells well.
