I think this thesis could be expanded to complex applications as well. For example one can use Word out of the box to write documents. That is the application's "one" purpose.

You can customize things such as the themes, but it does come with one preinstalled and selected by default. If people needed to download a "default theme pack" and then configure the default theme in the settings dialog before they could even write the first document I think many would abandon it very quickly.

I do disagree with parts about manuals though. Many applications need not only manuals, but whole series of books written about how to use them.
