I don't think anyone will be able to find out easily since this communication is encrypted. Who knows what the random bursts of data from some IoT device are?

I don't think anyone will be able to find out easily since this communication is encrypted. Who knows what the random bursts of data from some IoT device are? I can guarantee someone built a way to enable telemetry and diagnostic data into these devices "to improve user experience". It wouldn't take much for another engineer/sociopathic PM to enable it across the board (telemetry is now opt out) or change the sampling frequency or storage location.
