Please don't be stupid, Ambient != Morphos.
Ambient is an independant binary that replace workbench, just as Magellan, you don't have to link anything to it, only things MosTeam will have to do, is to release modifications they will do to Ambient.
You can use good old workbench instead of ambient if you want.

And if MosTeam don't want to release modifications they will do on Ambient, they always can find an agreement with David...

So understand that Ambient under GPL licence is really a great thing. Cause now anyone can try to improve it now and later.
I even think it should have been GPL far much earlier.
