Moreover, I think WD defense here will be that while you could, you did not have to plug your WD device to internet, in order for it to serve its purpose. They will try to argue that the majority of their offer is hard discs, and if your drive has extra ability to connect to internet, that's extra feature.
Yes, but that "extra feature" is most probably the main reason that model was bought instead of a cheaper model without a network connection. That is, that "extra ability" would be in fact the main differentiator of that model.
