What apple sell is something that is accessible to the majority and usable by most. Their sales are testament to this as is the fact that several ios apps are generally higher quality than their android equivalents. This is a natural consequence of the average ios user spending more on apps. There are no two ways around that.

As a counter to you headphone jack argument, i could equally make the case that many phone users care about their phones working, not much else. Apple's products are quite durable and many here will attest to using laptops from 2015-2016 and phones equally as old.

The short story is that apple provide products and services that people value. Period.
