If my phone automatically recognizes addresses but refuses to recognize the world’s leading map service and instead sends me to the App Store to use their second rate app, it’s certainly an ad.
It seems that you are unaware that Google maps uses location data to make ads follow you around. That seems like a pretty good reason for Apple to protect its users from Google’s data collection machine.
I want google maps to use my position data so that I know where traffic jams are in real time. It has saved me a bunch.
Apple Maps still sends people to strange places when you leave the city. (Apple Maps once sent us to the middle of a farm field, which was funny at the time, so I was glad it happened.)
