I picked up a nice four probe wireless thermometer today. The big advantage is a long-range base station with an actual display and controls that work without a phone app. I tried to connect their phone app to the actual device and it wanted me to set up an online account.

No.

Let me make this real fucking clear: THERE IS ABSOLUTELY NO GOOD REASON THE INTERNAL TRMPERATURE OF THE TURKEY IN MY OVEN NEEDS TO BE SHARED WITH A SERVER OUTSIDE MY HOUSE. NONE FUCKING WHATSOEVER.

"What harm is there if...?"

Wrong answer. This information is not relevant to anyone but me. Not every moment of my life, not every data point around me needs to go beyond my property line. This telemetry does not need to exist and it's taken for granted that it should by people who do not act in my interest.
