I suspect for long term goods that are below some cost, it's just cheaper for people to own them vs renting over the lifetime of the device. A corporation will tend to finance the capital cost of the good if it's renting, then needs to pass on the interest costs of those goods to the renters. On top of that a rental corp also need to maintain techs to install/remove appliances. It all adds up to higher cost to rent than own in this area.
