The problem with data center water usage is that it is unnecessary from the PR point of view. Data centers can run on air cooling just as good, but more expensive. For all I know, we could also do just as good without data centers, like we did 20 years ago.
With agriculture, water usage is necessary as eating is not something optional and everyone needs to eat to survive. From the PR point of view, of course. We couldn't live without agriculture, as we had agriculture 20 years ago too.
Golf courses are unrelated as they don't use nearly as much water as agriculture or data centers.
PR is everything, the narrative is what makes the difference. There is a lot of hypocrisy in this field, which is why I try to avoid it, but there is also some truth in it - we really didn't need that many data centers 20 years ago.
Golf course water usage vastly dwarfs data center water usage. Google used something like 1 billion gallons a year for their DCs. Single golf courses in arid regions can use upwards of a hundred million gallons a year, and in those areas there can be dozens of courses. It's not even close in terms of water usage.
Golf courses in the USA used about 2.1 billion gallons of water per day circa 2004 [1]. In other words, the annual usage of Amazon's datacenters per the article, 7.7 billion gallons, is less than the amount of water used on just American golf courses in four days.

"More expensive" means spending more on air conditioning. Ergo more electricity used, higher electricity demand, more natural gas burned and carbon emissions, higher consumer power prices. So a different kind of PR disaster.
The difference in energy usage won't be noticeably higher for PR purposes. Of course, the difference comes at a price, cutting which is the main incentive for water usage.
