I'm sure some companies, especially product led ones who sell one-off purchase items and services probably do waste time and money investing in marketing to compensate for a poor product service or positioning.
However, given that the aim of marketing per se is to identify, anticipate and satisfy customers wants in a sustained and profitable manner, I doubt any company that uses marketing to sell a crappy product / service would be the most profitable as customers will have no loyalty past their first purchase. For these companies, some original thinking in terms of new products albeit tailored to the existing or potential wants / needs of its customers might be warranted - there's no point promising what you can't deliver afterall - just ask Google. For everyone else, I guess there's always room for original thinking terms of how to satisfy and communicate with your customers, even if you have a great product.
