The device is presumably listening and recording everything and you can bet your last dollar there is fine print in the TOS that says Altman actually owns everything you say near the device and can use it for whatever he wants.

Oh, you thought you bought the device! Silly peasant! you just have the privilege of paying me to rent the device from me. Remember you will own nothing and will be happy.

Given the almost universal negative press about Altman, I wonder how many people would actually want a device from Sam 'let me scan your eyeballs for make believe money' Altman in their home.
