Reciprocal Public License I may as well tell my sad story. A few years ago I helped a friend write some software for the relatively poor school district where his wife was teaching. Being naive, we put it under the GPL. A couple of years later we discovered that another school district had paid a programmer to add all kinds of bells and whistles to our programs. We approached that district for a copy of the derived work only to be told 'tough shit'. Why should we help the kids in your poor district compete with the kids in our rich district. We went to a lawyer who told us that we were screwed. Since the district that had modified our code was not distributing the modifications outside their district, they didn't have to make them public. Once something like that happens to you, you tend to notice stories about it happening elsewhere. So I have heard lots of stories about where others got caught in the same trap. And of course, there are probably lots of cases where someone derives a program from a GPLed program and uses it for commercial advantage but no one ever finds out because they don't publicize it. It was precisely this problem that led to the creation of the RPL. The GPL says you have to make you source available when you distribute your code but you can deploy it throughout an organization, no matter how large, as a closed source binary. The RPL draws the line at personal use. Today, if I don't care whether the people who use my code give anything back, I use the AFL. When I do care I use the RPL. I guess it shows that I still really care about this stuff. Thanks for listening. BTW - This story has a happy ending. Tim Hogan of AZ Center for Law in the Public Interest, one of the few lawyers who is such a genuinely good person that he is almost a saint, got the whole discrepancy between dollars per student in different school districts declared unconstitutional.
