They say GNOME isn't a copy of macOS but with time it has been getting really close. I don't think this is a bad thing however they should just admit it and then put some real effort into cloning macOS instead of the crap they're making right now.
Here's the thing: Apple's design you'll find that they carefully included an extra margin between the "Don't Save" and "Cancel" buttons. This avoid accidental clicks on the wrong button so that people don't lose their work when they just want to click "Cancel".
So much for the GNOME, vision and their expert usability team :P
The founder of GNOME, Miguel de Icaza, stopped using Linux in favor of macOS in 2014 iirc. That makes me guess that the macOS design was at least acceptable to him. Maybe the visions were similar enough.
