Indeed but this highlights a fundamental issue with phones (and all devices): because Apple can continually monetize their devices with locked-in app stores and a litany of services etc they can easily afford and are incentivised to support devices for a long time.
Device makers third-party to platform ecosystems, like Microsoft to Android (but not Windows) find it extremely difficult if not impossible to gain these sorts of long-term monetisation which incentivises maximizing profits on the sale and then immediately dropping support.
