At least they've managed to be consistent with the rename. Compare this to Packages, which is called "packages", or "software", or "software install" or "packagekit".
Gnome do that with a crap load of their software, i guess they think it is "user friendly".
For example the binary for their file archive program is file-roller, but the entry in XDG compatible menus are Archive Manager.
Frankly i find that Freedesktop has been another example of "the road to hell is paved with good intentions". More and more Freedesktop projects reminds me of the kind of Windows stuff i moved to Linux to get away from.
'Files' is a much better name than 'Nautilus', IMO.
If you've ever spent some time teaching Linux to a non computer literate person, you come to appreciate sensible does-what-it-says GUI program names and the non-obvious names start to stick out.
And a special curse for all those people who decide to name their programs in part by the language or toolkit that it uses. What on earth are you thinking? Users don't care about your little details, you are just making things awkward for them.
How is a new user supposed to search for help with Files? Including the distro name doesn't help. And if the rename is complete then no-one should be calling it nautilus in the forums either, so knowing that it used to be called something else doesn't help.
Call it something like Nautilus File Manager or Gnome File Manager or Fedora File Manager.
