Guix doesn't prevent you from using proprietary software. It gives you all the tools you need to use package modules published by other people, or to package them yourself. This is free software after all: you have the freedom to use Guix for any purpose including the installation of non-free software.
I'm not just saying this to make a nitpicking point: Guix makes it easier to, say, build a custom kernel using the same reliable and hackable mechanisms Guix uses for Linux libre.
It's just that the Guix project itself won't recommend projects that extend Guix with package definitions for non-free software, nor will it include said packages by default.
