It may be that the public is seeing dollar signs and even more congestion when driving a car is made more difficult. Maybe it's their hard-earned money going into developers' and contractors' pockets through crony capitalism and public-private partnerships. Or they may see government run amok using their money without their permission. And then there's an overly controlling government trying to run other people's lives. Of maybe they just want to be asked. Lots of reasons why any city would want to fight a Metro take-over.
Times may have changed, but mass transit hasn't.
