diomus: That URL refers me to "past on-going disputes". When I move on to locate and read Drobe articles referenced there, I get "Castle conference transcript online", which offers nothing useful.
I then re-trace my steps, and try "Castle spills beans on ROL dispute".
I assume that is the Drobe article to which you refer. It mentions ROL failure to pass code back to Castle as only the third of three concerns. (My understanding is that failure to pay license fees was the primary, if not sole concern - I'm sure anyone can work out why failure to pay license fees might be a concern of the head license owner).
