Kildall was not some ignorant yokel from the backwoods. Besides, titans of the computer industry do deals with yokels all the time.
In fact, Kildall did later make a deal with IBM to sell an IBM branded CPM/86 for the PC. Consumers had a choice between IBM PC-DOS, and IBM CPM/86. The former was $40, the latter $240. People (like me) chose the cheaper one, because nobody could explain what was better about CPM/86. And the rest is history.
Maybe that is the misunderstanding that kept this discussion alive for so long: I'm not trying to privilege-shame anyone, just questioning the claim that it did not make a difference at all. (Actually I think that privilege-shaming is a really stupid concept, it won't ever achieve more than make its targets bitter or cynical, if it has an effect at all. It's not wrong to take an opportunity, just don't force it through improper means)
