I refrained from going so far in part because there's places you can still get great info on things like pihole, which would violate the interests of those departments.

But my gut says that it's not that google is defending the sanctity of such results, but that those results are an annoyance and not a real threat, so are just off the radar. When someone with enough sway wants them gone, I've got no doubt they'd be nerfed too.
