You know, you joke (I think?) but data center companies could genuinely at least open up for tours to try to appeal to the public, if public approval is apparently such a concern. It's funny that they haven't done it at all yet.

Think nuclear power plants in the 60s or 70s, many of them were open for tours or school field trips or such to try to make them more appealing to the populace around them. I haven't heard of a single DC doing the same thing, unless you're a potential customer. Isn't this stuff kind of basic?

Or build a park on top of the datacenter as a living roof?

Maybe even use the waste heat to help grow things in cold, dark climates?

It’s pretty different; but locally they covered a good chunk of a freeway with a very nice park to mollify the residents.
