The movie is a FANTASY about a made-up universe in which the decisions made by the characters are NOT stupid or unethical. It is not a morality play.

The world created by Sorkin may be too much like the real world for you to see it as artificial. But the rest of us are thinking "Of course that wouldn't happen, but wouldn't it be nice if we lived in a world where it could?"

Suspend your disbelief and go with the flow. I suppose you had problems with "Dave," too. If not, why not?
