As one of those users I'm still rocking my iPhone 11 and am perfectly content sticking with it The phone works. Telegram and Whatsapp works. Slack works. Safari still runs great on the web on the very few websites I use or browse. The longer I can use this without feeling "forced" to upgrade, the happier I'll be.
What apple offers me is peace of mind and stability. That's all I want from a phone.
I'm under no impression that my phone will continue to work until "the end of time", but if I can get 5-7 years out of a device then I think I got more than my money's worth. The last phone I had before this lasted 2 years before it became practically unusable.
