I expect that the overwhelming majority of the users don't want to see
the C source, but then, the vast majority of computer users use
proprietary software.
I think Emacs should (and does) really make a special effort to go out
of its way to encourage users to access the source code.
I think it is enough to help users look at the source code
once they decide to download it.
If you build and run Emacs uninstalled, this works automatically. We
could fairly easily make it more convenient for those who run
installed Emacs and unpack the corresponding source in their home
directories.
To go further than that would do no harm, but it could be a lot of
work. I suggest that people do the work if they want to.
