The big question is why fight over this, let him sell MUI for shareware to the Amiga public. The only thing Amiga has that Morph doesn't have is the name. You got better Hardware, to a better price.

IMHO it would be better to relese Morph 1.5, let stunts sell MUI for himself. Even if it will harm MorphOS some that even Amiga can get the latest MUI it can't harm Morph more than no more relese.
