It's like Linux users who scream about Arch KDE Plasma being better than Kubuntu XFCE++ and change their entire GUI every year. They're obsessing over rounded corners lining up. None of this matters that much.
It's more serious on iPhones cause it's glitchy in ways that will interfere with basic usage, also yet another "we need old phones to feel slower" update.
Really hilarious to complain about inconsistency in macOS and then encourage jumping to linux where you have one GTK app, one QT app, an electron app, and some secret fourth thing all running simultaneously with zero consistency or adherence to any kind of human interface guidelines.
How many? Many are using chromebooks and not complaining. Many use Linux and not complaining - as I work at a University.
A majority need only a browser.
