> I think of that bottle of ersatz Worchestershire sauce whenever I hear from Linux advocates who say that some piece of GUI software is as good as a big commercial project in the GUI realm. I don't think that this is at all fair. Some anecdata: I can't compare GNOME with macOS, as I haven't used either, but when I switched from Windows 7 to Ubuntu/Unity, I honestly felt that Unity was far superior both in terms of usability and degree of "polish", to the extent that during the transition time, while still dual-booting, I futilely tried to make Windows more Unity-like. Further counterexamples: Firefox vs IE, VLC vs Windows Media Player, etc. (Yes, in most of these cases the FOSS version has/had a large organisation behind it, to some degree, but then so does GNOME, at least for the moment.)
