Anec-data: I purchased a cooking device for my parents in December and it has a single button to turn it off. The only way to use it is with an app which requires a login to the company's service. The device even has local bluetooth capabilities. You may be wondering, "What is this device supposed to do?" and the obvious answer is: "It's supposed to boil water." The real answer seems to be, "it collects usage data about customers boiling water."
