Your analogy doesn't work. Here is a better one:
Somebody breaks into a combination-lock factory and steals the list of serial-numbers and their associated codes. They then proceed to use this information to break into peoples homes and rifle through all their belongings.
Don't you think that a home-owner who bought this lock thinking it was secure is going to do something about it?
The company selling the locks now has a couple of problems: the public image of their company has been tarnished, all the the locks they have sold are now insecure and a lot of customers now want their insecure locks exchanged for secure at no cost. All this will hit the company hard financially.
