Google Drive/DropBox and OneDrive has continued costs for the hosting provider and for this reason a subscription makes complete sense.

A better analogy is Office 365. Traditionally preputial licenses were purchased. Now consumers have become accustomed to purchasing access to the desktop applications through a subscription.
