Did not you read MR today? People trust Google with their data more than they do Apple. So being reliant on Google service is a good thin. Besides it's a really good service. It'll find anything you need to find, tell you when the establishment is open, when it is crowded, when was the last time you visited it, reviewes and photos etc. And everything is up to date.
Accuracy of the survey notwithstanding, I don't deny that google maps is an excellent service, but that doesn't mean that Apple Maps is all that bad. It's pretty reliable in my country (Singapore), and I think that's really the key threat to Google. That Apple Maps is good enough that people decide they don't really need all the extra bells and whistles that come from Google Maps, and are content to use the preinstalled default on their iPhone because really, what most people need from a maps app is to be able to tell them how to get from A to B.
One cool thing is that I can go "Hey Siri, how do I get to XX location" on my Apple Watch and it will bring up turn by turn walking directions on my wrist. It's those little refinements that Google services don't get to enjoy by virtue of being relegated to a third party app on the iOS platform. And looking at the google services I do use, many of them are more out of necessity than any "pure joy". And as I type out this response to you, I remember that a lot of my ambivalence towards google products is primarily due to the poor state of support for their iOS apps.
For example, I use the gmail app because that's the only app that works with my school's google account, but it lacks basic stuff like supporting group emails (I ended up using Cardhop to get around this), and support for the files app only came recently. I use chrome on my Mac because my school uses google docs a lot and it's better than IE on my windows device, but I prefer Safari on iOS for ad-blockers and reading list. Speaking of which, their google drive apps are very bare-bones compared to the browser variant. Passable for viewing documents, impossible to get any serious work done, which is the opposite of Apple's approach (excellent native apps, crappy browser versions of their apps and services), and I find this goes a long way towards reinforcing my decision to go all-in on the Apple ecosystem. Everything is just more seamless.
I use google classroom for posting assignments to my students, but the app is noticeably missing the ability to reply to students' comments. I watch YouTube a lot (because that's where all the creator content is), and I pay for Premium so I don't have to deal with annoying ads, but it took Youtube a good 5 years to support PIP, and they especially went out of their way to neuter the apps (like Protube) that did. Youtube Music is a joke (no split-screen support), and you would think that my music video playlists or listening history in YouTube would find a way to sync over, but no.
Google assistant is a non-starter for iOS users. I have also switched to DDG for Safari, and the instance there is any opening for me to replace another google service with an Apple-equivalent one, I will.
