Absolutely true

It has nothing to do with the aperture. The aperture gets opened
when you twist the lens onto the camera, and stays that way until
you take a picture, press DOF preview, or remove the lens. A loss
power will not cause the aperture to change size.

Actually, a lens with a large max aperture, say f1.4, will allow more light to enter the camera while composing than a lens with a smaller max aperture, say f3.5. herefore, a larger aperture lens will have the effect of making the viewfinder brighter.
