The difference is that much of the communication on that end happens in backchannels, directly with the regulators, in secret meetings, without any possibility of public scrutiny.
(When that isn't enough, the firehose of paid advertisements gets fired up to convince the public, instead.)
They all have a closed cooling loop, but almost all of them cool the exterior condensers with an open cooling loop.
Which draws from the watermain, sprays water on the hot condensers, the water evaporates, cooling the condensers. This is done to reduce their electric bills, because condensers operate more efficiently when they are cold.
The fully closed-loop data center, with air-cooled condensers is the exception, not the rule. Because it sucks even more electricity than a regular one, due to its less-efficient cooling.
You are spreading falsehoods, while also accusing people who are factually accurate of being foreign propaganda mouthpieces. This is at best, ironic and jingoistic, and at worst...
Also, you are arguing jargon...and data centers use completely closed loop designs where it makes sense (very cheap power) and use what you describe where it makes sense (with more expensive power and cheaper water). Finally, nothing you said disproves that there is a significant propaganda effort to demonize datacenters by a foreign power.
The dirty water bit is the most ridiculous thing. It's meant to paint the picture that the data centers themselves are using the water and dirtying it, when in reality the cause is the development of the actual buildings and infrastructure, which would happen with any industrial development!
All the arguments I see against data centers are arguments against industrialization. There are also arguments against capitalism and wealth inequality, that I sympathise with.
