Nonsense. That's not how the GPL works. There are special provisions
for non-GPL Operating Systems. Any code that is NOT part of the OS
must be opened if linked with Ambient. Ambient can link with MorphOS
as much as it likes, it makes no difference at all. If it did, there
wouldn't be any GPL programs available for any non-free OS... Now,
what that MorphOS team must do is to bundle and distribute Ambient as
a contributed application, not as part of the OS.
