Sure, it is nice to have the source code, but the idea of having source code available to the public, to me, (...and sorry to get philosophical) is that it can "sum up" to bigger thing and that can derivate into other things. The idea is not to have the source code for display, it is to allow it to grow and help the people that uses it.
Sure, it is MS Word 1.1, it is useless today compared to Openoffice, it is not the better example
