I would change this to: You have direct access to the source code. If poor/lack of documentation is a barrier to you using that application then look in the sources how it works.

Of course active open source authors welcome feedback and it is part of the community thing. But if I dump my development on the internet and never look back again it still is open source but there will be no community thing from my side.

Not that this is my intention with my SDCC developments right now, but someday I may retire my involvement and can only hope someone else will pick up where I left just as I picked up where others left.
