Yes, there are just two generally usable mobile OSs - ios and android. The only way to not share you every living moment with google while still having a snartphone is to have an iphone.
It's fucked up that's the way world is, but it is the way the world is.
There is a better way: Google-free Android. You get to use/keep one of the many supported Android devices without giving either Google or Apple insight in whatever you happen to be doing .I've been doing this for more or less as long as I've used Android, i.e. close to 10 years now. Back then LineageOS was still called Cyanogenmod. There were - and still are - alternative AOSP-based distributions which do more or less the same thing. These are Google-free by default, is you so choose you can either add the Google bits ('gapps' - a package containing the Google services framework and Google apps) or a free-software alternative which tries to emulate GSF, or none of the above. Nae lairds, nae kings -> nae Apple, nae Google (to paraphrase Pratchett)
That's what I meant by "generally" usable. You can install Lineage. I can as sell. But most people can't.
But the worst thing is that to get most use of Android, you have to have Play store and attached surveillance services. There's a lot of cool stuff on fdroid, but your city's public transport? Your bank's app? Your local taxi's app? Your city's meal delivery app? You're not getting that without Google Play.
You can get some stuff from sites like apkmirror, but that's at the risk of getting malware (again, the two of us can see what's malware and what's the actual apk, but most can't) and at the cost of automated security updates.
I lived like that for a while, and it's not worth it. Maybe if you don't mind you're smartphone is actually a dumbphone - which is a good thing for some people who want it that way because of minimalism and somesuch, but most people don't.
It's fucked up that's the way world is, but it is the way the world is.
