Water use is a pretty close proxy for power use which is a pretty close proxy for how much computation is happening. I can totally see why a company wants to keep this info secret. Competitors would really like to know.

#12Is data center water use not closed loop? If not, why?
You could spend more electricity if needed to up the airflow to get the same cooling power without humidifying.

#13Is this water even “used” in the same sense that water is used for bathing or agriculture? Where does the water go? If they simply take in cold water and release hot water, that water is still available for other uses. Or do data centers use evaporative cooling just like power plants?

> Or do data centers use evaporative cooling just like power plants? Yes. Not always, but evaporative cooling is much more energy efficient than heat exchange to outside air. That said, stories about data center water use are a distraction from much bigger water consumers like golf courses and agriculture (e.g. to ship alfalfa to the middle east).
That's something of a fallacy of relative privation. When water is scarce, all frivolous uses should be under scrutiny. The others you mention have been well-known for a long time. The current stories simply highlight a new consumer people haven't thought of before.

#16Why do companies actively lie in their advertising about being eco-friendly, instead of just keeping a low profile? Is it because we tend to focus only on current events and quickly forget their past track record? Indeed, if people soon forget the lies, the risk is minimal.
It’s an explanation of why so many companies suddenly appeared to go “woke”, or why they did a complete 180 when the political climate changed. Even powerful companies like Apple must grovel for favor.

Even in case of evaporative cooling the water is not used. It's returned to the environment.

#19Water use for all of AI is inconsequential compared to agriculture.
In addition, water is almost never wasted, only moved around.
Energy is the important input.

One reason is that large institutional investors or lenders enforce certain agendas by only giving money to companies that meet certain criteria. Thus companies will posture themselves as meeting those qualities to attract money and investment.
