Agree, Water Injection takes up "Air Molecule Space".
You basically reduce the chamber volume for air (which is needed to make the power when the right amount of fuel is added) so you possibly reduce the knock tendency but give up power doing it. Crappy fuel or the cost of fuel causes people to do lots of weird band-aids.
