If their basements are not climate controlled then I can see the need for a dehumidifier. Most of the time if a basement is somewhat finished and/or has heating and cooling then it should be comparable to the rest of the house. Lacking that, yeah, the conditions in an unheated/uncooled space are going to be all kinds of weird.
My basement does have heating and cooling, but it's still a basement and still needs a dehumidifier. Truth is, I closed (left just a tiny bit open so some air gets through) all the basement vents for the summer because the air conditioning was actually working too well and it was too darn cool. When I had the heating/cooling fellow out for the regular six-month system checkup a month or two back, he recommended closing the vents in the basement for the summer period. Said the ductwork running through the basement adequately cools that area without the vents needing to be open. My dehumidifier cycles off and on adequately.
