As a counterpoint: I purchased office 365 purely for Onedrive. I was totally happy with my ancient office products (2013?) before, but I wanted to get some cloud storage with good synchronization and sharing tools as well as a good web interface. The Onedrive/Office365 offering provided that.
However it might be true that I'm the exception on this, and that most of the Office365 licenses are sold to corporations that are more interested in the basic office tools.
