Not nasty, but unnessesary, for the both of us. He was a non-technical auditor, and was hoping to put something damning on his report to justify the expense. He "cleared" that item after discussion, but I did not want to have that talk about the "unofficial.iso" again. And since I +-always take expert mode for other reasons anyway, having to select "non-free" repo on devices with non-free components from inside the standard installer is no big detour.
