>So I guess it was him who he gave the 2006 MUI4 source code to them and there was nothing illegal in developing the derivative per se, opposed to what some claim in this thread.

So, in the end it would appear that the only real impropriety is the numbering scheme AND the borrowing of code.

Which takes us back to the question of why they would want MUI compatibility (specially MUI4 compatibility) and that is obviously to run software written for MorphOS.

Flattering AND troubling.

Ah well, soon two out of three available new AmigaOne systems will be supported by MorphOS.
So...maybe the users should just switch.
