I don't think I see how KD is to blame for this. The Miner's Revenge concern actually garnered a substantial amount of advocates for its removal, despite how foolish the whole thing was. KD didn't just waffle under the first sign of a complaint, they let the maze run for the year and simply didn't return it the next year. Cedar Fair was probably the ones who told them to remove it. Also, the maze itself didn't return this year due to ADA guidelines, not because of the mine controversy.
On the other hand, BGW removes all this after four complaints in a gazette article, which were from a different group for a different reason. The two things are hardly related.
