Evaporative cooling needs less water mass and less surface area for the same cooling effect. They could simply use bigger heat sinks outside the building and have a bigger water cooling system to make it closed loop, but they don't want to do that.
I think evaporative cooling is more effective.
Right, that's what they said. For a closed loop, because it's less "effective", you need a much larger system. It's more expensive to build and requires a much larger footprint and corporations like Amazon would rather save a penny than do anything to reduce their harm.
