This happens all the time. Recently I bought a sous-vide machine, and realized that it would phone home with details of my cooking, along with the WiFi AP. Essentially someone at the company would have an idea of my location, along with whether someone was at that location, and maybe my food preferences.
The idea that this kind of analytics is not opt-in, and that you are essentially forced to provide this on a product that you paid full price for is ridiculous. It may feel like an overreaction to worry about someone knowing what you are cooking, but how do you guarantee that this information will not be combined with other pieces of data by a third party to create a more complete picture of the user?
I am as shocked as you are are, but apparently they exist: https://www.cookmellow.com. A bit like a remotely-programmable slow cooker, but then for the limited amount of ingredients a sous-vide will cook.
