A random people on hn, presumably not a data center manager, is not "making a threat" by talking about potential second order effects of data center policy.

No despicable data center apologist has ever suggested that communities shouldn't negotiate the best deal they can get to compensate for the incurred costs and externalities.

Why do you feel justified defining what terms a community can agree to when considering hosting a data center? Do you not believe the democratic right for them to self-govern.
