I think the idea is that with increasing mass the contribution to the acceleration made by the spring decreases in magnitude for one reason and the contribution to the acceleration made by the fluid decreases in magnitude for that same reason and another reason. The first reason is that from F=ma, the greater the mass for the same force, the smaller the acceleration. The additional reason for the case of the fluid is that, if we release the object from rest at maximum stretch, from the same position with different masses, even without dampening, at every position of the object on its way to the equilibrium position, the greater the mass, the smaller the velocity at that position. With the fluid in place, the smaller velocity results in a smaller retarding force. Thus, greater mass leads to less dampening.
