Strong disagree on gmaps, especially with Apple Maps available for iOS users. Gmaps is strictly better, but not enough to balance their incentive to truly abuse that data against me.
Apple is strictly worse on location data collection than Google, so you are not solving GP's problem. The OSM apps on Android are viable options for preserving privacy. Apple Maps is not.
Huh? Android is the epitome of the surveillance panopticon. Google has every incentive to monetize that data for their ad sales targeting. Apple doesn’t.
Beside that I’m a big fan/contributor/user of OSM (maps.me is my app of choice there). But if you want to go with one of the big, polished players, I chose the one that has little to gain and much to lose from abusing my personal data.
Apple's search ads are projected to be one of the largest online advertisers in terms of ads revenue in 2020 (they have larger advertising revenue projections than both snap and twitter). Device sales in general are dropping so they are expected to continue to invest in this area of their business. Given that Apple is a large organization known for their lack of transparency, I would be very surprised if they weren't already doing shady things with user data for targeting purposes.
Can't is the wrong statement. The can be. Whether they choose not to or not is a different conversation, but technically they definitely can tie these together from IP address alone.
I get frustrated with the hoodwink that Apple seems to be playing, as they move to services based revenue I have no doubt these lines are going to get blurrier and blurrier.
You can't sign in to Apple Maps. Apple doesn't know who or where you are, except via a random frequently rotating identifier.
Google pushes you hard to sign in with your Google account, tracks your searches and location, and associates that data with everything else they know about you.
All of the things you listed don't apply at all to OSM maps apps and are opt out in Google maps.
In Apple's ecosystem you cannot opt out of sending Maps queries from maps links to Apple at all. Additionally, if any app at all requests your location, iOS sends your location back to Apple, and you cannot opt out. On even Google-flavored Android devices, you can choose not to send any location information to Google at all.
