> I think this is because the demand is so extreme for datacenters now that companies are building them in a manner that disrupts the environment around them.

This would make sense if the ones being targeted are the ones that do this, but that isn't the case. Moreover, those would be simple to address, e.g. pass an ordinance that prohibits long-term operation of fossil fuel generators, defined as operating them for more than 40 days out of each 700. Or impose a reasonable decibel limit as measured at the property line.

Meanwhile people are proposing "data center moratoriums" and so on, even if the data center would be built in a non-residential area with a closed-loop cooling system and generate its power from a completely silent and non-polluting solar+battery system. Which makes it pretty obvious that the motivation is something else.
