Tangentially, I had to argue on a very popular Amiga forum that a guy that ported some GPL licensed software to the system should also release the source he built his binaries from, all while several users were openly mocking me for even suggesting it. It wasn't a piracy friendly forum either. They'd vigilantly delete links that could lead you to 35 year old Kickstart ROM images, and merely suggesting that someone download a cracked copy of some game they already owned was frowned upon. It can be a very strange community depending on where you look. That said, I don't mean to say that I think the licensing terms of this project are unfair. It seems reasonable if you believe you owe a lot of your work to someone else that you want it to generate some public good that will benefit everybody.
