They figured they'd spent the budget for the quarter for PR proclaiming their
commitment to security.  Remember - they're nowhere near as committed to
security as they are to the bottom line.  A $20M PR campaign will sway a lot
of managers, while a $200M project to actually fix things won't be noticed.
Which would *you* choose if you were them?

(Note that this is heavily dependent on corporate culture - for instance,
if some VP at Google tried that same money-saving stunt, he'd probably get
called in, pointed at the "Don't be evil" sign, and told to find some OTHER
way to save the $180M...  But as far as I know, there isn't any such sign
in Redmond....)
