pychan general

pychan is a lightweight (~150 Python LOC and ~450 JavaScript LOC) Python imageboard that uses AJAX requests and JSON responses. Although it lacks some of the detailed features that 4chan has had worked in over the years, it has reached a state that it can run faster and more reliably than 4chan's imageboards.

Not really. Some people would like to share GPL software binaries and maintain proprietary control over the associated source code. The GPL states they are not permitted to do this and as a result, they'd forfeit their licence to share the GPL software.
