That's the thing. If they are truly goods, they cannot be in between! Otherwise they are being handled as services and as such they will be terminated at some point. So unless we redefine the word, a true "purchase" can never depend on future actions from the provider (like renewing some DRM).
So no purchasing a warranty or service contract?
Who still purchases a warranty a la carte?
Hasn't it been clearly established for at least a couple decades now that all of these are de facto scams?
