I'm not talking about the recycling rate. Even if that goes to zero it doesn't change the story here. The point is they aren't boiling the water, for the most part. They discharge it in a pipe.
And? I really do not think anyone is complaining here about the water disappearing into thin air or its atomic components or whether it goes in a pipe or into the moon. The definition of using water is quite clear (you can no longer drink it) and unless I am misreading you are totally distorting it.
Yeah I think you are misreading it. The manner in which a data center (or a thermal power station, or any highly energetic industry) "uses water" is literally the water disappears into thin air, and doesn't come down again until it's thousands of kilometers downwind.
