"Vi" is not "just naming the editor what it is", it's a relatively distinct short name that doesn't actually mean anything unless you know the reason for the name (which I did not for years after being introduced to it).
At some point recently, Ubuntu stopped using "nautilus" as the name of the file manager, and now it's just called "files". Except, wait, that's some kind of alias, so the process name is still nautilus after you start it. If you don't know the relationship between the GUI name alias, and the literal process name, how are you supposed to figure it out? How are you supposed to search for info or help about "files"? It's too generic.
