Even so, I'm not sure how solicitations to sell something (Read: advertising) is the same as the actual or perceived goodness, functionality or reliability (read: Quality) of a commodity.
The advertisement is not the same as
"the goodness" of a commodity, but it affects the consumer's perception of
"the goodness" of a commodity.
I don't think there can be a truly objective measure of "the goodness" of a commodity. At some point, a somewhat arbitrary decision has to be made about how to weight the measures of reliability (mean time between failure), feature set, price point, appearance, etc.
