I will take a look at the original article.
But again I'm going to restate that the article you posted uses tech oligarchs as primary sources. Which just on the face of it looks like green washing.
Edit: I read the paper. Yeah the conclusion is tech is seriously underestimating water and carbon footprint. We don't have exact figures because they don't disclose them. But from what we can gather the information they are giving us substantially down plays the environmental impact.
So, we don't have exact figures. And acting as though we do using tech oligarch statistics is greenwashing 🤷♀️
For anyone following along.
