The traffic is Keurig DRM to force use of official pods

Assessment

The DRM reading traces to the poster himself, who offered it as a half-joke: 'it's dumb, avoid it, it's just DRM waiting to be enabled so you are forced to use official Keurig pods or something.' It was not presented as a finding, and it was then repeated in some coverage as if it explained the terabyte. There is no evidence linking the traffic volume to pod-lock DRM; the K-Supreme SMART's BrewID does recognise pods and the device syncs recipes and usage data to Keurig in normal operation, but routine telemetry is kilobytes, not ~1 TB, and the poster's own leading explanation is a bug, not an intentional feature. Rated weak: a real, sourced remark, but thin and explicitly speculative, and a poor explanation for the observed behaviour.
