I gave a talk in China 5 years warning about this. http://tech.qq.com/a/20140527/035512.htm I asked vendors to make changes to their products, such as planned obsolescence so if the manufacturer goes out of business and a device doesn't hear from the mother ship for awhile, all internet connections are killed for good. Also, to set smart defaults so that even when not configured, it won't allow this behavior. There should be a list of more in the article but you'll have to translate to see them.
