Half the Duplo and Technic are now licensed, but I suspect the Technic licenses may be nearly free or even paid to Lego - they’re selling Ford cars to Ford fans.
The licenses obviously don’t cost a ton as the price per piece on the Duplo is comparable to other “sets” - the “big box of parts” is cheaper as always, but I wonder how much of that is “we out left over pieces and spend no design time”.
