I'm not sure this is a counterargument, but if a company did this in an open way I could trust, I would buy EVERYTHING from them. Fridge, washer, dryer, dishwasher, televisions, small electronics, cars, whatever. You name it I'd buy it. I don't have enough information to determine how many people are like me, but the profit you could make on me as a customer would be ridiculous. You'd get the kind of platform loyalty that Amazon and Google dream of. I'd probably even be happy to share some personal information with you in a way that I controlled that you could turn around and sell. The sense of autonomy, privacy, and control is that valuable to me.
