The complaint is not that you can't have both. It's that you can't have either. Even if you don't want the benefits of this or future updates you can't keep the current functionality. That's called taking something away.

No, it's still the same argument. Games and movies I already own are not services. Netflix is a service. I don't think Sony has the right to disable products I've bought and own any more than Amazon has the right to delete ebooks from people's Kindles.
