This is not how an open-source project should be.

Precicely! I have never heard of any other open source project with CLOSED source documentation.
Perhaps Walter knows of such a project besides the WP-34s project? I'll bet if a poll were taken of those for or against opening up the documentation it would be almost unanimous in favor of OPEN!
