Not intentionally but yes it has a positive attribute if it happens on occassion regardless. How many millions of these units are in circulation that are vulnerable, how many others from other companies are built similarly? If someone wanted to start a war, attacking someone's food supply would help them immensely. And if this was just someone's blog post and bug report of "I can hack some refrigerator!", how many store owners and food suppliers would ever even notice or take seriously the risk? They spent money for these fancy systems that promised to help their business, and it ends up being a massively liability.
