I really like the contrast between the strategic aims, and negotiating levers, of Gates & Jobs in this story.

Both want the same software to be in the Mac world for its 2nd-order benefits; neither needs to monopolize it.

Both want a good deal, which Gates pursues by a sort of "labor-theory-of-value" and Jobs by assertion of Apple's proprietary rights.

(It does sound to me like Hertzfeld could've gotten more with the right ask, but getting to tackle the problem, and see his solution out in the world, was of even higher value to him.)
