My point is not exclusively advertising but that it is wishful thinking that companies always make sensible decisions. Often enough, useless or even harmful things continue to be pushed through, simply so that one doesn't have to admit to oneself that one has made a mistake. They would rather try to achieve a positive result with larger investments after all, which usually fails and leads to even larger losses, than to exit early and get away with smaller losses. Therefore, the statement that a reasonable company would not act this way is not covered by reality. Companies should not act this way, but they do.
