I don't think that snooping on the connection explicitly reveals what app is being being launched - it just reveals the identity of the developer that signed it. But I agree that if the developer only has one App, then it does sort of give the game away. Yes, and DNS is another example of Telemetry. What is google doing with the data they get from their DNS services? I have in the past examined other devices - A QNAP NAS for example, phones home, sending the last part of the device MAC address. It did this once a minute from when it was turned on. I stoped using it - I do not know if this has changed in recent QNAS versions.
