Id disagree, if your a decent coder, shareing a script aint a problem, you just have to actually accept people are going to use what you give em, and you cant just recall it, unless you made em agree to some tos or somthing when they got it. Its why you can still use an ipb 1.x, despite ipb no longer being free.
People though will only get the dj panel as it is, no bug fix's, no securety updates, no new features etc.
