[AB] Shaw showed up and took my SB6120

Shaw randomly showed up at our door to replace our modem. They said our SB6120 would stop working in a few days and they were upgrading it to a DOCSIS 3.1 modem. I never had any problems with the SB6120 and it was a great standalone modem. It turns out the "DOCSIS 3.1" modem they replaced it with was some refurbished smelly old DPC3825. What the heck? I'd consider that a downgrade. The thing has already dropped connections on me twice after a hour of use (in bridge mode). Has shaw showed up to take anyone else's SB6120's. Is there any truth that they'll stop working on shaw's network soon?
