I think many data centre opponents understand that being opposed to AI is not sufficient to halt a local project, so it is noise, water use and power consumption that they latch onto - although, in jurisdictions without plentiful water and clean power, those two reasons are quite valid.
In my own local community, there’s vocal opposition to a proposed data centre that is next to Lake Ontario, 500 metres from the nearest residential neighbourhood, on a brownfield site with 500 megawatts of clean power capacity. None of that makes a difference to those opposed.
