In my opinion, that's dangerous at least. So I prefer other tricky distinction. Big publishers and their mimetic branch---the so called “indie” publishing---only cares about two things: s
ells and reputation. They want to live _well_ and get social recognition from the _good_ books they publish. If one day the software communities develop some desktop publishing or typesetting easy-to-use and suitable for all their _professional_ needs, we would see how “suddenly” publishing industry embraces free software.
