We're already on a slippery slope for fetching the non-free source
ourselves to process them, but I'd argue that this doesn't steer users
toward non-free software, but rather empowers them to free the original
source of the software they use.

In an ideal GNU FSDG world put forward by some proponents, we'd not even
let users' machine fetch the non-free source and instead host it
somewhere else, ready to be used.

I don't really see how "obsfuscating" the non-free source we process
makes it much different, or how having an easier access to that non-free
source from the CLI would steer users toward "using" non-free software.
A source is not a usable (executable) form.

But anyway, with that opinion of mine expressed, I've reverted the
offending bits so that we can move on, knowing that once we get the
strings_all.tar.zst locales data planned in future releases, it won't
matter much anyway.

See the result in v4.
