Usability has taken a nosedive with the rise of web apps. Every company wants to have their own special branding in the form of a "design system", and there's a whole industry of designers coming up with different non-standard ways to do things.
It's not just web apps. macOS has a haphazard mix of old-style checkboxes, large iOS-style toggles, newer SwiftUI smaller iOS-like toggles, old menubar checkboxes, new iOS-control-center button toggles, and a HomeKit universe of ad-hoc toggles designed for touch that make no sense for a mouse UI.
