The local population is probably allowed to complain that you built the reservoir with toxic waste, too, or that you filled the old well with construction debris.
But anyway I personally would find someone offering well water if I don't like the reservoir. And I've been using DuckDuckGo exclusively for search since they first appeared, so I've never had to deal with what Google's doing. I know the reservoir exists, but I've never drank from it.
That sounds like an argument to never depend on Google for anything ever again under any circumstance short of severe punitive legislative action.
Especially in Google's case where they've invested so much into remaking how society works worldwide. To expect people to simply accept anything and everything Google wants to do just because they're a private business regardless of how many billions of people their actions affect?
Lunacy.
How you want public perception to work and how it actually works are different things.
