You have said at least twice that the feature to set Google Maps as default has "Never" been available. You are wrong and it was pointed out to you prior to your last statement that it has "Never" been an option. The instructions were also provided. "Never" is one of those words that one should not use unless they are sure it applies. In this case, "Never" does not apply.
In IOS 8, here are the instructions to set Google Maps as the default mapping app:
1. On your iOS device tap on any address to make the operating system launch Apple maps app. You can use the following address as well. If it doesn’t work in Safari then copy and paste it in Notes app and try again.
Apple
1 Infinite Loop
Cupertino, CA 95014
408.996.1010
NOTE: You can use any address
2. When in Apple Maps tap on the ‘Car’ icon to tell the app to start routing.
3. Now on your screen you will see three tabs. One of them should be for ‘Apps’, tap on it.
4. From the list of apps select the Maps application you want to use instead of Apple Maps. Simply tap on the Route button located next to it. On this screen you will also get a list of related apps that are available in the App Store.
Once you are done with the steps above your iPhone or iPad will always launch Google Maps or the app you chose whenever you will tap on an address.
This "always" worked in IOS 8. Once the user selected Google Maps in this way, the default moving forward was changed and IOS 8 "always" opened up Google Maps when navigating. Apple won't let us delete it's mapping product. After IOS 8, Apple won't let us select any other product as the default app nor will it let us delete Apple's mapping product. We purchase the phones. Yet we cannot set the phones to use applications as default apps. Someone with far more time and money than I have will someday challenge this practice, win and there will be a large payout. It's like telling me I can purchase the car of my choice but must always use the manufacturer's tires, air freshener, etc. I have to use products that meet standards to keep my warranty but I can use other "default" products on my car. I guess there must be a safety issue, too big for me to understand, for it to be impossible to use other apps as default apps other than Apple apps.
The problem with all large companies is they become large by listening to their customers but once they become large, they listen to internal voices who know more, who know better and are not concerned with what customers want. Over time, they lose market share for the same reasons they were able to gain it in the past; their competitors listen to customers better than they do. Apple is over the hump and not listening to customers. The old days are gone.
