a) SGI no longer cares about GLX that much. All of OpenGL has been
handed to the Khronos group.
so I'm not sure who can relicense the code, it might be possible for
the Khronos group to release a relicensed version
if they could be made care.

b) lawyers cost money.

I think the intersection of people who care and can do anything about
this is negative..
