I'd say that's half the problem. The other half is the regulatory environment causes the risk to land completely on the municipality (ie the community). If a datacenter gets approved, and then turns out to have something like subjectively objectionable noise, the datacenter will point to the approval containing no restrictions on noise, or engineering figures showing that it technically meets some requirements. At which point the municipality will basically be prevented from creating new regulation to prohibit the offending behavior. It's like if the kid next door got a loud car stereo, so you worked to get the city to pass a noise ordinance. But then you were told that your neighbor specifically could continue blasting his music since he bought the stereo system before the ordinance was passed.

And that's before getting into federal nonsense where if a community does successfully reign in a datacenter, there is a chance the operator could appeal to the federal regime to override the local laws (as we're hearing about with the on-site natural gas power plants and whatnot). It's best to just not allow any kind of foothold in the first place.
