If I have two PDF viewers, should both be called "PDF viewer"? Gnome seems to love hiding the actual names (the gnome document viewer is actually called evince).
View it this way. If I’m a new user to Linux, KDE tends to come with far more apps than GNOME, with names that are often so opaque every app is a mystery. And not in a good way.

You nailed it: GNOME targets new users. KDE doesn't. The advantage of having unique names is that you can actually talk about them, and that includes finding documentation and solving problems via a search engine.
Try finding anythng useful when your query is based on a generic name, e.g. "document viewer crashes".
Applications in every KDE system menu and search box result list have descriptors about what the application does that follow the application name. Didn't mean to be rude but it's honestly not hard to read the descriptor textsbefore clicking on something.
