They are assuming that these devices would be used long enough for tin whiskers to become a problem. I seriously doubt that RoHS will be causing more waste - because at the point that devices become unusuable, they are on in the trash anyways for completely unrelated reasons (think: bezel to large to be popular, plastic backshell instead of metal or glass, device is too thick, device is too heavy, ...).

Tin whiskers continue to grow even after you device is in the landfill. You basically have a dust of tin which goes into landfil.
