It probably stems from the well-known history of the start of the company. Who knows who started Dell, McDs, any number of SSD manufacturers, Lenovo, BlackBerry, etc.? I guess we all know about Microsoft and Bill Gates, but their story trajectory went the other way (more corporate). So, I imagine people say that because something Steve Jobs or Ives said or was recorded as saying resonated with them, and thus they share that deep belief.
