I believe a good bit of it relates to "switching costs." Consumer brands that offer a new product to compete with an existing one often do it at a discounted price. The companies essentially must pay a fee to the consumer for the time, effort, and uncertainty related to trying something different.
An example is wanting someone to read a book you think they'll like. It costs you nothing to give this advice. If anything, you stand to gain in something like reputation or ego if it's helpful or something they enjoy. But it potentially costs time they they might've spent enjoying something else even more.
