Yes Overflow, it's true, people do have the physical right to make those changes, because the source leaked. But you won't see people like Olaf working on it, and you won't see good things happening on GitHub or other public development venues, until the intellectual property rights are finished off once and for all.
There are countless examples of so-called Internet "takedowns", where enthusiast projects have sprung up on the Internet with *perhaps* questionable legality, and all it took was a threat to get them to stop. This disgusts me on two levels, that the threat would be made, and that the threat would be taken seriously. Nevertheless, what we want is every person who is willing to work on AmigaOS, working on it. We don't need a further division between those who will work on what they see as "illegal code" and those who will.
