Because we don't have that special sort of brain that thinks turning such a simple useful tool into a commercial behemoth is a good idea? I doubt anyone there really things there is a useful purpose to it all, but they have to keep it in motion to keep their pay coming in.
the world is what you make of it. make something, sell it for exactly what you need to buy bread . I don't see why being so cynical is necessary.
Right now your boss has sold something, and pays you with the remainder. Is he a bad guy?
What's wrong if you did the same?
