Doing as exhaustive of a search as I could, I found a couple of interesting things. The Sony version of the parable seems to center on the Walkman (as opposed to a camera), which was built in the late 1970s, and either Akio Morita or Masaru Ibuka (co-founders of Sony). However, the earliest reference on the Internet to it I can find is from September 2002 [^1], about a year after the iPod was released, making its origins inconclusive. The fact that it is linked to multiple founders of powerful technology companies suggests to me that it is apocryphal.
Well, the story might well be completely made up, but the chances are higher that it was made up about Sony not Apple. Probably around the time of when the first Walkman was released.
Let's not forget that early Apple was modelled after Sony of the time. Also, under the context of Japanese culture the kind of attitude displayed by the 'boss' in the story is less striking or unusual.
