What's especially nuts about this to me is that macOS supports static scrollbars! System Preferences → General → Show Scroll Bars → Always. Or, leave the default settings in place, but plug in a mouse with a physical scroll wheel. So it's not even that they're only using one platform, but they're only testing the platform with default settings with the default hardware. And we're not even talking about an obscure setting buried three levels deep, it's right there in the general pane!
