One thing that could explain this dichotomy is that writing such an article for oil refinery would be expensive task. Because data for such research may not be readily available online (not focussing on intentions). Just a guess. You will find more articles about things that are easy to write about. If an article requires lot of field work, on foot research, talking to many people and synthesize and piece together disparate information in a coherent manner, don't expect it to be commissioned.

I at least expected a description of the conditions inside data centers that portrayals in movies in TV shows always seem to get wrong: how _loud_ and _cold_ they are.

Only colos are cold, though. Private hyperscalers keep theirs nice and hot.
