They actually make their products more expensive than necessary by making the client pay for something they have no use for: advertisement - making it less competitive by this extra price. I avoid heavily advertised product when I have a choice (and when not, then it has just no benefit for the company to pay for advertisement: I'd buy it without adverts for the same price.)
