If consumers cared about small phones Apple would still make the mini series. It's hardly Apple's fault the biggest phones are the most popular. In fact, they were late to the larger phone sizes, as the iPhone 6 shipped years after Android started going big.
Some consumers clearly do care, but mega-corporations aren't content with making a profit - they will kill profitable products because they're not profitable enough.
(Apparently the 12 and 13 mini had about 5% of iPhone market share in the year they were released [0]. Does that mean they were profitable for Apple? I don't know, but given how many phones Apple sells, I believe that even 5% iPhone market share would be profitable)

Still using my 12 Mini on iOS 18 - I won't go without a fight.
