I have not seen any information that light from these satellites could scatter and brighten the night sky a significant amount. This article just shows their paths are visible on a sensitive image, but the paths themselves amount to tiny fraction of the image. There is no claim they added significantly to the overall exposure. With their being bright planets and stars already present in the sky, I don't expect they could.
