Does anyone know why in the 5 years of the maps app it was never updated? Is it possible Google didn't want to maintain the app on iOS? We are assuming Apple had some control over whether the Google app stayed on iOS but the contract was up, and it's possible Google didn't want to renew. After all, Google has a web based app that works on iOS... Maybe that's all Google wants to give.
