I remember the fracking roll out here. The companies involved directly handed checks to local residents, promised to train locals for new jobs, paid to fund schools, and so on.
These companies have a lot of money behind them - if they're not willing to put in the effort to convince local residents that the data center will be good for them, I feel like that's on them. They could easily do some handouts and fix this. Offer to pay extra taxes to the state or whatever, fund a new power plant, pay everyone who lives nearby the DC some thousands of dollars, whatever.
