I suspect these controllers were mostly being used for telemetry (getting notified if they lose power), not remote control. But they were still vulnerable to zero-days if not updated. Kind of the same story as all the other IoT stuff that has turned out to be vulnerable.
Not if there’s no control hardware for it to be connected too, a telemetry sensor in no way needs the ability to even influence the mechanical function of the device.
It’s almost like having basic appliances connected to the internet is a bad idea. Outbound sensor data? Yeah, ok, maybe. But inbound commands?

But then how will we get security updates?
You keep a hammer next to the electronics. If they act up, they get smashed. That’s all the security needed.
Doors that exit can also be used as an entrance.
