The worst part about it is that it was then used to champion asinine legislation that hurts the people who want to do things right.
So now every municipality who wants to buy some old poisoned dump on the cheap (because it's poisoned and that restricts development) and not be idiots with it (e.g. turn it into a park or a parking lot or some other use not involving serious excavation) can't actually buy the land and do so because no sane company will sell it to them because they could just go and do something stupid and then turn around and make the company pay.
It's like the municipal equivalent of taking a free boat off someone's lawn in order to get an engine core and then acting like you got swindled when you find out it costs money or labor to get rid of a boat and then having the state pass a law making boat owners liable for disposal in perpetuity.
