Is hardware replaced under trade up nothing more than a paperweight?

Hi.

I've got a 60E that I'm replacing under the trade-up as it is EOL next year July.

The reseller told me it would simply be deactivated which is fair enough that I don't have to ship the old one back, but what exactly does that mean?

Is the old device going to be nothing more than a paperweight going forward, or could it be used as a basic firewall without all the subscription features. I.e. could I used it at home and create forward/blocking rules etc.

Or do I simply send it off to an e-waste recycling center?
