Isn't that the point? In the story the engineers weren't designing a tool well-suited for the customers, but for whatever abstract scenarios they had in their head. In the open source world it's more reasonable and common to design a tool not predicated on the predominant models and workflows. And every once in a awhile those experiments result in something very valuable that helps to break predominant paradigms. But in the commercial space solving customer's immediate problems in a manner that is intuitive for them is paramount.
