You did leave out the not-inconsequential fact that almost any retailer would accept a return of the Keurig if the customer found himself dissatisfied. So, the consumer is out a return trip to the store, at worst.
Your claim that a free market implies “perfect information” is bunk. It no more requires that than free religion implies guaranteed entry into Heaven or free press implies accurate reporting.
Comcast has been building a relationship with such groups via its Internet Essentials program. As I understand it, it was compelled by the government to offer low-cost Internet to low-income families with kids in school, so it created Internet Essentials. But a household can only qualify for the program if it has not had Comcast cable for at least three months prior to applying. Since Comcast generally has a de facto monopoly in most areas it serves, and Internet is damned near indispensable, the three month rule keeps the number of eligible households to a bare minimum. But Comcast uses Internet Essentials to promote its humanitarianism and to build bridges with the minority non-profits.
How long now until the company screws millions of users by abandoning Google Voice? It has years since Voice innovation ceased, and promised features were never produced.
