I feel like this is always the case with new technology. People had the same reaction to the invention of the printing press. New is scary. It doesn't mean there aren't valid concerns, but unfortunately this feels a bit like an inevitability. The focus shouldn't be on stopping it, but how to maximize the gains and minimize the losses to the local communities where these are being built.
You're not doing your side any favors by using the printing press of all things as your comparison. People very legitimately don't want things like fracking in their area even IF it brings a boatload of jobs due to the costs on communities. Datacenters might not be as potentially destructive, but they're also a massive net negative for the community in many real world ways. If you want them to "maximize gains", then…
No they aren't. Datacenters are air conditioned buildings that consume a moderate amount of power and generate a moderate amount of tax revenue through a small number of middle class jobs. They use a negligible amount of water compared to golf and farming and produce a negligible amount of heat compared to cars.
