Slightly off topic: but doesn't backdoor mean that there's a particular party that has control over the backdoored software? Here it sounds like the device is calling home... or is that sufficient to be called backdoor?

Yeah, backdoor usually means that the device accepts credentials from a third party, and not sending them reports.

I suppose you could interpret this "backdoor" as third-party access to the data, rather than to the device.
