I used to work nextdoor to the broadcast headquarters to an old sports cable network and their satellite uplinks. They had several diesel generators on site to ensure power never went down else their entire network went dark. If power was lost, they had batteries for immediate power that lasted long enough for the generators to kick in. When the generators kicked in, it went from being a nice quiet area to being in the parking lot of a truck stop with all of the engines running. If these new datacenters are powering themselves with generators, then yeah, I'd not want them to be around me either.
I think your ire at the discussion is pointed in the wrong direction.
