For an Android user, iOS offers better privacy (which can change at any time), but it also comes baked in with better support for some open protocols. (SMB on Files, and CalDAV/CardDAV for Calendars/Contacts/Notes integration). This has been the case for years, while aspects of the 'walled garden' have eroded over time.

It's natural that this huge Android regression might be enough for someone to dip their toes into the other side.
