They have the same general characteristics as the local NIMBY class, but I think I'd want to see more evidence that they are actually members of that class. It's a substantial accusation to make without evidence, especially since you purport to link that to tech companies being NIMBY by policy -- again, a claim I've not seen evidence for.
Only one half of the equation (new residential) is affected by NIMBY-ism. No new residential is fine, just don't build more office space then. That requires local governments not to endlessly expand spending though, so obviously impossible.
