Interfaces were WAY more consistent than they are nowadays even when taking into account some applications slightly altering their themes. One application using a listbox instead of a tree (like one of the Microsoft examples in the site you linked) does not make a UI inconsistent (even as the wrong control, the listbox still looks and works exactly like the other listboxes in the system), it only makes it an odd/bad choice. And from a quick browse, most of the issues mentioned there are things like that (including, amusingly, a ribbon-like interface in Windows 3.1 in the tabs section[0] :-P).
IMO the fact that someone cared enough to make a site about what is largely nitpicks like this shows exactly how these stood out in the otherwise consistent landscape of UIs in the 90s.
Nowadays such a site would have 99% of every application released. It could even be automated, just somehow track all new .exe files in GitHub, MajorGeeks, Softpedia, etc and add them automatically to a hall of shame list, chances are even without human supervision the overwhelming majority will be correct :-P.
