Genuinely though, if anyone is unable to fathom why so many people buy iPhones yet continue to use all Google apps, this is one of the main reasons.
Whilst I'm currently still stuck on a Pixel 5, when the day comes that I move back to iPhone I will also not be using anything related to iCloud outside of device backups. Previously used iPhones from the 3G all the way to the 12, and my overall experience was that one year iCloud works fine, the next it doesn't. It continues to flip flop and then out of nowhere a major issue will pop up to remind you of how silly you were to trust such a service.
Again, I know so many on here hate Google for selling your data, but most people are fine with having their interest linked to a randomised ID which can be voluntarily wiped with a moments notice. People who are fine with that will get a much nicer cloud experience in return. That's not to say Google are the only alternative either. Microsoft have some very compelling apps themselves now, as they too look to exploit the services market.
As I still use Windows PC's regularly, I'm seriously considering going over to Microsoft apps for a trial run, especially now that Edge has caught up and arguably surpassed it's competitors.
