People are pissed that Big Tech/VC/SV has taken over seemingly everything, enshittified it, and enriched the enshittifiers (while the economy has gotten worse for nearly everyone else, and Big Tech's fucking insane leaders have gone full steam ahead at destroying the social contract--literally in some cases by eviscertating whole swaths of the American federal government, and probably illegally at that--and funding the campiagns of those who seek to shield Big Tech from liability.). All this despite having come onto the scene under the guise of "Don't Be Evil" and "Think Different." Data Centers are the most visible manifestation of this ugly side of Big Tech/VC/SV, and ugly in and of themselves; thus, it is not surprising that people roundly reject them. There is (because of the timing of this inflection point--upward--in data centers and inflection point--downward--in economic sentiment/reality) probably also some post hoc ergo propter hoc or temporal-correlation-as-causation going on here too.
The thing is, it takes a pretty coherent worldview of Big Tech, VC economics, politics, etc., to state above as such, so I am not surprised (in a time when education, too, is being destroyed--often by Big Tech itself) most people can't articulate it. 1 in 5 american adults is functionally illiterate, after all.
