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.
