If what my parents do, in their clumsy sort of non-technical way, in the normal course of taking pictures and videos with their $75 point and shoot and downloading a few movies to watch without having to eat into their monthly bandwidth quota everytime my mom wants to watch one of a handful of old movies is "data hoarding" and exceeds the capacity of the machine a "power user" is using, then I think that both of these descriptors have lost all effective meaning.
A better analogy would be somebody who fills their trunk with their weekly groceries and commutes 60 miles total per day being considered the same as either an F-1 driver or a long haul trucker -- when their use cases for their vehicle are pretty normal.
