They did Apple because Google orpahned their maps app on the iPhone by giving turn-by-turn navigation capabilities first to their Android app. Classic strategy tax that backfired as the most used maps app on Apple is the default app and Google has a fraction of the users on the iPhone.
Google also required user location data which Apple was not prepared to give. And Apple of course didn’t want to be in a second place position (apart from navigation there were also the better looking vector maps being reserved for Android etc).
