Between any of the big 3 companies putting out major OSes (Apple, Microsoft, Google), Apple is the best for sticking to tried and true designs. It's certainly gotten worse the past couple of years (like the Photos app redesign they immediately changed again in iOS 26) and I hope with their new design lead he can pull things back to somewhere sensible, but compared to Android or Windows it's not even close. I used Android for the better part of a decade and every year they'd completely redesign the notification shade, the settings app, they'd switch the SMS app out for Hangouts, then put you back on Messages, then rename it, then change the logo/branding, then redesign it again, etc. Everything was endless changes for no reason, felt like a constant beta.
If you look at the basic iPhone apps - Messages, Settings, Notes - prior to Liquid Glass it's been pretty much exactly as it was when Jobs showed it off at the iPhone reveal 19 years ago.
It's a bit like adding new emojis in an OS release. There's been reports that new emojis are one of the drivers for getting people to upgrade. No one cares about a zero day security flaw, but that new kiss emoji everyone wants.
Apple has released incremental upgrades to macOS for years, and I've never heard this criticism of them. On the contrary, I ofter hear people missing Leopard design, and when UI has changed I've heard pushback (ie, when System Settings was renamed and redesigned). On macOS people care about the apps and interactions, not wether the buttons got a new look.

I agree with this. New emojis are new functionality; you can now express something you couldn't. A zero day security flaw brings no new functionality. Equally, updates to to apps and interactions bring new functionality. A re-skin of the OS doesn't.
But, having worked with users I've seen first hand out tons of internal improvements are ignored while one small UI change makes 'everything seem new'.
