To a very large extent people aren’t even aware most of the stuff would work without Google services, even on Android, even without microG! On the other hand there is stuff that works so well that people take it for granted and it feels kind of ridiculous to read “After 20 minutes to an hour, your device should display your current location.” in UBPorts documentation. There is an alternative with network assisted services from Mozilla (probably a little better for privacy) and even /e/ is still leaking an awful amount of data to Qualcomm but eventually I guess this is one of the problems that will somehow get fixed, the users won’t accept 20 minutes GPS fix time, not even 1-2 minutes.
On the other hand some things probably won’t have good free alternatives. I’m waiting since way before the days of the smartphones for some interface that would show you where your (well GPS tagged) pictures were taken on a map or let you search some radius around some location or something. I’m talking mostly about local simple picture viewers/organizers - many do have such options but it’s only for one directory with a couple hundred pics you took from a trip, they’re not meant to scale to 20 years of pictures. Lightroom’s Map module almost does it (forget that it also uses Google Maps for the map itself) but still doesn’t scale well and it chokes on any reasonably sized catalogue even with a very powerful computer. Google Photos does it effortlessly. It finds the pics from name of places and it has since recently an explore maps feature in Google Photos that looks exactly like the feature I’m waiting now for more than 15 years from any decent local picture catalogue/browser program.
