Ditroff per cpu was cheap. I was part of all those negotiation. There was a buy in that way high and John points out. Actually there were two - one to get the sources for your first internal cpu and another for the redistribution rights.
My memory of the first license for the original ditroff 1.0 typesetter was 5k (which included the new C compiler) although it did drop later when it went into the toolchest. But There was also redistribution fee also which iirc you worked off / creditted against like license fees.
The entire v7 OS redistribution fee was on the 50-100k range (I've forgotten but am likely to have that in my att files somewhete) - which was after the 25k single cpu source license. The original binary per cpu redistribution license started at 1.5k. Which when a minicomputer was selling at 150k was not terrible. The problem was a PC at 5k.
I was in the room at Riki's Hyatt in Palo Alti when that was all negotiated. This would lead to the Sys III license. It was at that MTG Gates famous looked at the rest of us and said "you guys don't get it. The only thing that matters is volume". He wanted to pay $50/copy max.
Anyway troff was much cheaper than the whole OS license. The per cpu charge was very small as I said my memory is it was $5 over the base OS license.
Actually It was very cheap. $5 a copy if I remember correctly Masscomp and Stellar just ate the cost. The adobe transcript license was also nominal. In both cases we realized it was cheaper than trying to keep two separate streams and figure out which systems we shipped it too.

As I recall, AT&T wanted about the same amount of money for ditroff as
for the entire UNIX release. So, of course no UNIX vendor was going to
double the royalty they paid to AT&T for every customer, for a small
improvement in a utility that most customers didn't even use (troff).
