Some parts of some craters are in permanent shadow.
This is true, but the phrasing "might be present on the sunlit side of the Moon" is problematic and reinforces the belief (also reinforced by the phrase "dark side") that the Moon has a light and dark side. (At least in the case of 'dark side' an argument could be made that it means 'dark to (historical) human knowledge.' It's hard to defend "sunlit side.")
Tidal forces from Earth have slowed the Moon's rotation to the point where the same side is always facing the Earth—a phenomenon called tidal locking.
