@aral does macOS force-retheme third party app icons? No! What they do is design a consistent set of icons for their apps, and provide clear guidelines for third-party designers to design their own.
That's exactly what upstream GNOME folks are doing now. Pop!_OS should embrace that.
If you don't like a particular icon in an app that hasn't been updated, nudge the developer to redo the icon with the guidelines in mind. Same as you would if you don't like an icon of a macOS app.
@bugaevc No, but good luck getting an app that doesn’t follow the HIG into their App Store. So I guess that’s the road that GNOME Software will take to ensure consistency?
The default on macOS and iOS is consistency due to the culture/focus of the platforms. The default on Linux is inconsistency (a trait that is often lionised and labeled “choice” instead of criticised).
Given we probably don’t want an authoritarian App Store model, distributions enforcing consistency should be applauded.
@aral not that many apps care about getting into the Mac App Store (as opposed to the iOS App Store); and I don't think icon style inconsistency has a lot to do with choice-as-a-user-feature.
I'd say consistency comes from developers (& designers) *caring* about it, caring about making great native apps that fit in with the platform. And of course from the platform providing enough tools & guidance to make it feasible for the developers/designers.
