I used to print t-shirts for a living. This site made the t-shirt forum rounds a while back as a time-saving way to convert art into screen-printable art. So to answer your question, the apparel decoration industry is a huge consumer of graphical applications that manipulate art into formats that can be output to a shirt for example. Considering a good shop does hundreds if not thousands of orders a month, subscription based auto-formatting is a pretty good deal. Also, there are freelancers and companies that manually create vector art from any supplied format. So these guys can use this as a streamlining/base-lining tool as well.
