People are more concerned with the direct material impacts of datacenters than more abstract things like slop and surveillance, those are actually afterthoughts. The more pressing problems are jacking up the price of water and electricity, generating noxious fumes and noise pollution, causing computing shortages, and all being done without paying taxes and with government subsidies.
Oh and it's being done to power machines that they constantly claim will take everyone's jobs and might end human civilization.
If datacenters were not a direct economic threat to communities I am skeptical that there'd be as much broad opposition to them.
