I won't submit to data sniffing from corporation, so "personalized" hardware won't make it into this area here.

By the way, this is not new either. In the 1990s Microsoft tried to convince people how great it is if their fridge gives data to MS so MS can order needed food etc..

Fast forward some decades - many don't want to yield any more data to private entities, no matter which alleged "benefit" this would bring.
