That's just the chicago theme I'va had for years now on my XFCE, I think it's a bit lame to steal that theme (not from Microsoft but the maker of that xfce theme), put it in a repository, give it a different name, and pose it as your own work?
The repo literally adds nothing, just a name change.
I think the main difference is that it’s a fully set up installable ISO of Fedora Atomic XFCE with the theme and other tweaks preloaded which is a convenient thing to have, I guess. Also they do credit Chicago95 pretty much at the top of the README.
