It's a little more nuanced than that. The simplicity enabled many more people to express themselves in contexts other than spreadsheets. The Macintosh, for example, ushered in the age of desktop publishing, which was a boon to writers and academics.

Practically speaking, I don't see that as having changed in Apple. They still see the gateway to creativity and self expression being ease of use, as opposed to some other values such as hardware compatibility or UI customizability.
