Fair comment.
However, unlike x86 and MacPPC communities, the members of the Amiga community, in my opinion, (given that it is smaller and has probably kept only the most hardcore amiga users from the old days) is probably perfectly capable of doing something with that source code, whether its producing applications that work better because they work with the OS better, or its producing patches to problems, bugs and (hopefully there wont be any) security problems.
I mean, nowadays, people who still use Amigas know how to get the most from them. They arent a stupid bunch, and I think they all deserve to play a bigger role in the development if they want to.
