you're not wrong. local governments often attempt to use unused property as a way to funnel much needed financial support into the city/state by ways of their own deception.
we'll sell you this property and you can do what you want with it. *some exemptions may apply
in this case, the buyer had enough "fuck you" money to see to it that this turned into a huge mess, ecological and otherwise.
that said. who's to blame? is it the government attempting to finance social programs for their city/state by selling unused property to companies? or is it the company that purchased the property and decided they don't have to follow the laws because they have enough money to do so and in turn destroyed hundreds of thousands of local ecologies out of spite?
personally, I'm blaming the company. they had no reason to do what they did other than to menace the locals.
sure the politicians aren't blameless, but they are operating within the laws.
