    The ammonia acts as both a base and a ligand. With a small amount of ammonia, hydrogen ions are pulled off the hexaaqua ion exactly as in the hydroxide ion case to give the same neutral complex.

    Because the hydrogen ions are being pulled off, is this deprotonation?

    Yes this is an acid-base reaction, not a ligand exchange, since ammonia is accepting protons it's acting as Brønsted-Lowry base, so the water is indeed undergoing deprotonation.
