I don't know the specifics of the non-free software Nix
Nix is completely Free software, released under the Lesser GNU General Public Licence version 2.1. So is nixpkgs, its official MIT-licenced collection of package definitions. (Guix combines both concepts into one repository.)
You might be confusing 'non-free' with 'does not follow GNU's Free Software Distribution Guidelines' (FSDG), a much stricter set of additional rules that dictate what every single installable package is allowed to be and do.
Nix/nixpkgs/NixOS have not opted to follow these unrelated rules; GNU Guix have. Both projects are Free software.
Both must therefore grant you the freedom to run non-free software; Nix makes this more convenient.
