Apple love to preach "the UI gets out of the way of your content" with each new redesign, but how true is that in practice? Let's compare the total height of the Safari UI with a toolbar, favourites bar and tab bar visible, across the three latest Mac OS design languages – Yosemite, Big Sur and now Tahoe. I've added a red line for emphasis.
It sure looks to me like the UI is eating more into my content with each redesign.
It may be a flaming pile of garbage, and native apps are preferred by users ux-wise, but if your business already has a web app for desktop. Are you really going to spend money developing and maintaining a native app?
The reality is most businesses will want to write and maintain single codebase, and PWA is the lowest common denominator. Apple is making the experience worse for it's customers by not forcing their users onto Safari.
If your functionality warrants being installed on a mobile device, then you are expected to deliver a certain level of quality for being on that device.
I have zero patience for cheapskate business douchebags who want to have their cake and eat it too, and I will not speak in their defence, not ever.
