Strange they haven't corrected it (put in the words) at Yahoo yet. I guess no one wrote a business case for it yet. (See Sunday's strip if you don't remember.)
Dilbert's competitive advantage within his subsidiary is he has a list of customers who bought the "glitchy" product. He and the other cleaners probably get a commision or PHB points for each "accident" scene they clean, so that would explain why he makes house calls before the police even get involved.
