- you can't install apps without an apple account(making the phone useless really)
- you can't download apps from outside the app store
- there is no security enhanced or de-appled version if IOS, while on android GrapheneOS and CalyxOS exist
- you are limited to Safari as a browser engine(no extensions).
Compare the actual features of Android vs. the actual features (instead of the marketing) of iOS, and it's clear that Apple doesn't care about user privacy. With Android, you get to choose which if any Google services to use. On iOS, you can't run any apps without telling Apple which ones, you can't get your location without also sending your location to Apple, and you can't practically run your own apps without fully deanonymizing yourself with banking details.
